1967 ELDORADO BROKEN POWER WINDOW CABLE

The red/white power feed wire going to the switch in the drivers door suddenly broke and my windows would only work by holding the emergency lockout switch. As it turned out the cable broke inside the rubber conduit which is about the worst place on the car to repair…

1967 ELDORADO CARBURETOR REPLACEMENT

I installed a rebuilt carburetor from www.carburetorcenter.com into my 1967 Eldorado today. It suffered from bad idle when fully warmed up at low RPM. It had a problem with the secondaries not closing properly and was worn out a bit. It's an easy install. The 1967 Eldorado uses a unique linkage for the transmission switch, which is a one year only item. Take good care of yours!
The Eldorado now purrs like a kitten again with its new Quadrajet. I now have two more carburetors to do - the 1966 has a stuck choke and the 1978 needs a new accelerator pump.... The video is also available on YouTube in 4K HDR quality...

WINTER PROJECTS FOR 2019/2020

In September I put my cars into winter hibernation and the projects for this winter will be:

1978 Cadillac Eldorado Biarritz:
  • Rebuild the Quadrajet carburetor as the car has some hesitation when accelerating from standstill. Probably the acceleration pump has a problem.
  • Check EGR valve.
  • The water pump is slightly squeaking (maybe I will have to replace it)
  • The AC controller under dash is sometimes making a ticking noise. Looks like a bad contact somewhere causing the setting motor to rattle.
  • AIR pump is making a light noise - a well known problem with these old pumps.
1967 Cadillac Eldorado:
  • Rebuild AC compressor as it blew its main front gasket a while ago.

MY 1967 ELDORADO BLEW A CARBURETOR GASKET (AGAIN)

Back in 2011 I had my carburetor rebuilt by a shop, which I used by the time, and before I did all the work by myself. When I got the car back from the shop, I suddenly heard a ticking noise, which came from the side of the carburetor and the car idled terribly. As I soon found out, the shop had the gasket and the metallic spacer installed in the wrong order and because of this, the gasket burned through, which caused a massive leak at the carburetor.
A new gasket was installed in the correct order then, and the car ran really good until recently, when the car suddenly had the exact same symptoms again…
I ordered new gaskets again and removed the carburetor from the car.

THE RESTORATION OF MY 1967 ELDORADO IS FINISHED

Yesterday was a very exciting day for me.
The restoration shop let me know that my 67 Eldorado was finished and ready for pick up.
After work my wife and I jumped into the car and drove 2 hours to Radstadt where the restoration shop is located.

I saw the finished car for the very first time.
The job Bernd Preussler and his small team did is amazing. The paint job is the best I have ever seen. Their commitment to details is outstanding.

THE 67 ELDORADO RESTORATION IS IN ITS FINAL STAGE

I visited the restoration shop to deliver the newly rechromed rear bumper to finish the restoration of my 67 Eldorado. Unfortunately the quality of the chrome job is not good at all. The chrome shop didn't do an acceptable job. Still I will install the bumper now to get the car home and will try to find a better shop to do it once again. Most people probably would not notice the problems in the chrome, but they are just not up to my standards :-(
The restoration shop on the other side did a fantastic job so far. There are some minor details they still want to address and the car should be ready for pick up sometimes in May.

Here is a short video I took with my phone at the shop when I delivered the bumper, showing the almost finished car. Make sure to watch in HD to see all the details

THE 1967 ELDORADO RESTORATION - WHAT WE HAVE LEARNED SO FAR...

LONG POST AHEAD!

Whenever you restore a car you can learn a lot about it. The ongoing restoration of my 67 Eldorado is taking a little break now, and here is a summary of things we have learned so far during the restoration process:

There seems to be a design and/or a problem at the front windshield which causes rotten floors and rust in the A- pilar:
Although my car is a low mileage car (28k miles) with no other real rust issues, the front floor of my car had to be replaced as we found out when the carpet was removed. I have heard some similar stories from fellow Eldorado owners who had the same problem with their cars. Some of them owned very low mileage texas cars and had rotten floors and/or rust in the A-pillar. The water seems to enter at the A-pillar and often causes rust through holes there. It can then seep into the car, where it ends on the front floor, from where it cant evaporate due to the rubber insulation used underneath the carpet. When the windshield on my car was re-installed, we made sure that it seals perfectly and we used some modern material to make sure there wont be any future issues. The front floor on my car had to be replaced as you can see on the pictures of my restoration gallery.

THE 1967 ELDORADO HAS NEW PAINT!

Evenings are very exciting for me since last November… The reason for this is because the restoration shop, which is repainting my 67 Eldorado at the moment, is always uploading pictures of the days progress to a web server after work.
Today was especially exciting. I saw the Eldorado in its new paint for the first time!
Doesn't she look spectacular in its fresh coat of "Atlantis Blue Firemist! ?
Bernd and his team did an awesome job so far as you can see in the restoration gallery.
There is still tons of work left - but everything looks very promising so far.

REPLACING THE FRONT FLOOR OF THE 67 ELDORADO

I was a little shocked today when I saw the pictures the restoration shop sent me of my 1967 Eldorado Repaint Project.
While the exterior of the car did not have much rust I was surprised that the front floor of the car had quite a bit of rust.
Some of the previous owners seems to have tried to stop the rust on the floor sometimes in the past by applying a good amount of rust converter, or whatever the black paint was , he applied over the rusty floor.
It seems that it did not help but just made the sheet metal oxidize underneath this sticky mess.

The restoration shop now started to remove this paint just to find some weak metal with some holes in it.
This is when they decided to cut the entire front floor out and replace it with some fresh metal instead.
They had to make a patch panel from scratch as no new panels are available for this car anywhere. The new custom made replacement floor was now welded in.
Like on the factory rubberized undercoating was reapplied underneath the car and the welding seams were sealed with seam sealer.

You can see all the detailed pictures in the restoration gallery here.

I hope this was the last unpleasant surprise for a while…

NEW PAINTJOB FOR MY 1967 ELDORADO

My 1967 Cadillac Eldorado was a completely original car including its factory paint job. It looked great from 10ft away and on pictures. But if you inspected the car closer, you could clearly see the many paint issues it had .This is the reason why I never showed the car anywhere. I have already fixed all technical problems and the interior is in mint condition. It's a very low mileage car with only 28k miles and it drives like a brand new car.
One of the previous owners of this car tried to touch up the paint in some areas but it was not done properly…
I bought the car in 2009, and since then I was planning to repaint the car to make it perfect.

Being a perfectionist I had a hard time finding a shop which is up to my quality standards and work ethics. During a photo-shooting I came in contact with a shop about 2 hours from where I live. My wife and I were invited to photograph one of the owners Hotrods and he also owns a Cadillac with a breathtaking paint job. While we were there I was extremely impressed by the cleanliness of his shop and the quality of the work I saw there and especially about the attitude of the owner Bernd. A couple of years later 3 of my cars needed some little paint touch ups which made me pretty nervous. But Bernd did the most excellent job on my cars, so that I asked if he could also do my 67 Eldorado.
Unfortunately a couple more years went by where I did not have the financial means to do the job.
Last year - out of nowhere I was contacted by an uncle I had not had any contact for the last 42 years after my dad was killed at a work accident. To make a long family story short - he "inherited" me a very generous amount of money - almost as much as I´ll need for the paint job of my 67 Eldorado.

Yesterday I delivered the car to the restoration shop.
After a long and thorough inspection by the shop owner, the restoration will start soon. The owner is optimistic that hopefully there wont be too many bad surprises hiding. He measured the paint thickness and found some evidence that some damage might be hiding in the right rear quarter panel. Maybe the car had a fender bender sometimes in its previous life.

The car will be completely disassembled. Front and rear glass will be removed. Fenders, hood, trunk and doors are coming off. The interior will be completely removed, but the body will stay on the frame.
Then everything will be taken down to bare metal by sanding, as its too cold to strip the paint with chemical paint stripper during the winter months.

Every step will be documented with pictures which I will post here on my website as well. So keep coming back to follow the restoration if you are into this kind of entertainment.

I´m so happy that the car will be fixed at this shop. It's the first shop I have no worries about the quality of job done. Bernd - the shop owner - is a perfectionist like me. He only accepts perfect quality and wont take any short cuts.

FINDING THE RIGHT COLOR…

The big question for me now is if I should have the car repainted in its original "Grecian White" color, which I am not exactly a big fan of, or repaint it in one of my favorite 1967 Cadillac Eldorado Colors "Atlantis Blue Firemist" which was a pretty expensive optional paint in 1967
When I asked my friends to help me decide, about 80% said I should paint it in "Atlantis Blue Firemist"… If I could go back to 1967 and order one from the factory I would probably order the blue one
I was also informed that the Cadillac LaSalle club does not deduct any points during judging if you do a color change, as long as it is done in a correct color for a certain year…
Being an originality buff - I´m having a hard time to do a color change though. My little son also wants to keep the car white - my wife would like to have it changed to blue… I´m sure whatever I decide - I will sometimes regret my decision. If I paint it in its original white I will always find the color on the boring side and if I paint it blue I will regret that I changed the original color…

A6 AC COMPRESSOR REPAIR - BAD BEARING ON THE 1974

When I bought my 74 the seller informed me that the AC compressor was bad and that it was disconnected due to a bad clutch or another problem. So I ordered a new rebuilt AC compressor with the car.
Due to all the other projects I never managed to get the AC back in fully working order until now.
Unfortunately the rebuilt AC compressor came with the clutch coil terminals in the wrong position. They are available with the terminals at the correct 10 o clock position or the 2 o clock position, which is correct for other years.
If the terminals are in the wrong position you cant connect the original wires to them as they are too short. With the high shipping costs it was no option to send the incorrect compressor back.

As it turned out the cars original compressor had a bad bearing and that was the reason why it was disconnected.

My friends Lucky and Steve were here to help me with the compressor project and so I took both of my compressors to Lucky´s workshop, as he has all the necessary tools and experience with these compressors from his own cars.
Originally I just wanted to turn the clutch coil on the rebuilt compressor into the correct position, but then we decided to rebuild the original compressor instead, because it still has the original decal, which is not available as a correct reproduction. All the available compressor reproduction decals are TOTALLY incorrect for the 1974 Cadillacs. The 1974 reproduction decals all show the wrong amount of refrigerant! They are also different in many other details. The closest match of reproductions for 1974 are the ones from 1972 Cadillacs…

We still disassembled the rebuilt compressor to "borrow" its pulley bearing to replace the bad one on the original compressor.
The procedure to be able to replace the bearing and to turn the clutch coil is not too difficult - but you need some special tools. Without those you cant do it. You´ll need a basic clutch puller / installer set for this job and some long nose snap ring pliers to get the retaining rings out.
First remove the shaft nut and the snap ring ( the rebuilt compressors always seem to come without this snap ring) and then pull the clutch with the special puller. Pull off the pulley and take the bearing out and replace it with a new one.
To be able to turn the clutch coil you´ll have to remove another snap ring. This snap ring was the biggest challenge for us. The shop manual lists a special tool for this which we of course did not have… It could be done with a very long nose plier as well, but we did not have these either. So it took us quite a long time to get it out with screwdrivers and self made hooks… You can then simply turn the coil into the correct position.
Putting it back together is pretty straightforward as well, but again you need a special installer tool to get the clutch back on and to adjust it properly.

I will now have to buy a new bearing so that I can put the rebuilt compressor back together and have it as a spare.
I have attached some pics from the shop manual which show how to remove the various parts of the compressor to remove the pulley and the clutch coil.

As always you can find ALL the pictures in my restoration gallery!

Once the snap ring is out you can turn the coils terminals to the 11o´clock position or the 1 o clock position. On the 74 it has to be at the 10 o clock position, otherwise the connecting wires are too short.

COLOR CODED VACUUM HOSES - BEWARE OF TERRIBLE REPRODUCTIONS!

Cadillac used color coded ribbed vacuum hoses from the 60s to the late 70s to make it easier to identify them on the vacuum schematics in the shop manual.
These vacuum hoses unfortunately get extremely hard and brittle over the decades under the harsh conditions in the engine bay. Often they literally break into pieces by just touching them.

On my 67 Eldorado I had to replace most of the vacuum lines when I got it - and it really has a lot of hoses.
When I searched for reproductions I could not find a really good source and I gave up.
At my ongoing project on my 74 another of these original lines fell apart while working in the engine bay. So I started to look for the correct hoses once again.
Soon I found a link on ebay to a well known seller, whose name I do not want to mention, offering the lines in all the colors I needed.
I ordered quite a few Ft of each color.
The seller describes them as factory correct and as a perfect part - see screenshots below.

As they do not ship to Europe, a friend of mine was so kind to forward the hoses to me.

When they arrived I was shocked - I have never ever seen a worse product.

The paint is peeling off or missing at all. As soon as you even slightly bend the hoses, the paint on the stripes just cracks and falls off. It could not be worse.
Also the hoses are too thick and the walls are to thick. The original hoses are quite a bit slimmer than these crappy reproduction hoses.

They also charged me for 15ft of red striped hoses but only sent 10ft. This was about the worst buying experience ever.
I´m trying to return the hoses at the moment - but communication with this seller is terrible.
I normally never criticize sellers here on my website and never leave any negative comments on ebay - but this is the worst I have ever experienced.

Shipping back these hoses will cost me at least $50 and I already paid $60 for having them shipped to me in Europe - with the import tax I will have lost $160.- for this BS… Money I would urgently need for some other parts… :-(

I´m now trying to find another good source for quality reproduction hoses. There is one Corvette parts dealer which looks promising as he offers some great kits for Corvettes, but they are all pre-cut… I hope he can send me some ft. of the hoses I will need - I hope that I will get a positive reply.

FIXING A LEAKING VALVE COVER ON MY 1967 DEVILLE

The right valve cover on my 1967 Cadillac DeVille always had a small leak and eventually some oil would seep down on the exhaust manifold and cause some smoke when it burnt.
The gasket was replaced a couple of times since I own the car, but it never was very successful in stoping the leakage.
After my last attempt it leaked even more than before…

The valve cover design of the 429 engine is not exactly the best from a technical standpoint. It's only held in place by 4 screws.

I did some research and tried a different approach this time to seal it.

First I used a different valve cover from a spare engine I have in my garage which did not show any signs of leakage.
I had to fully detail it first to make it look perfect. I repainted it with Bill Hirsch Engine enamel in the correct color.
I made sure that everything was flat as these cover often get warped at the bolt holes by over tightening them.
They checked out flat. I then glued the new cork gasket (I used a Fel-Pro gasket) to the valve cover with high temp gasket sealer. To make sure that it stayed where it belongs to I used a lot of cloth pins to keep the gasket in place.
I let it dry over night.
The next day I put some wheel bearing grease to the other side of the gasket and put it back on the heads. The grease helps to make sure that you can remove the gasket any time again.

I then tightened the four bolts to 28 INCH/Pounds of torque as specified by the shop manual. (thats 3,1 NM) I had to buy a small torque wrench for such a small torque rating first… I could have never guessed how much torque it is.

I then ran the engine and let it cool down and re-torqued the bolts afterwards.

After the first 25 miles test drive it seems that the valve cover is 100% leak free for the first time since I own this car.
I´m not sure what fixed it this time, but during my research I read multiple times, that for cork gaskets one should not use gasket sealer on the head side of the gasket, and one should only use grease instead. Some recommend that gasket adhesive (spray) should be used to keep the gasket in place in the valve cover.

edge
I know it looks very strange, but I used cloth pins to make sure that the gasket is glued to the valve cover properly…

REPAIRING THE 1967 CADILLAC AC CONTROL HEAD

The air condition of my Cadillacs always surprise in a negative way. Every spring something new does not work after I wake them up from their winter hibernation.
This time the 67 Eldorado had a new problem which I had to fix.

It suddenly only blew hot air out of the AC outlets. It did not change modes at all. That was a sign of a weak vacuum signal…

I started to inspect all the AC related vacuum lines of the car which checked out fine. Next I did the test I´m describing here in an older posting, as I suspected that the power servo had a problem.
I soon found out that still not enough vacuum was supplied through the transducer.

That meant that either the transducer could be faulty, the temperature sensor could be defective, or the dash control head would not work properly. I took out the temperature sensor of my 67 Deville to test it in the Eldorado but it did not change anything.

I then removed the control head and tested it with a spare one I once bought cheaply on ebay. It did miss some connectors and switches, it had some blemishes on the chrome and did not look good enough to install it into any of my cars. When I put it into the Eldorado anyway the AC suddenly worked perfectly again.
So I removed all the electrical parts from this working unit and transferred it to the perfectly looking but defective control head. After I had swapped all the usable parts I put the unit back into the car and I now have a perfectly working unit once again.
It looks like that there was a problem in the amplifier part which translates the signal coming from the rheostat into a current going to the transducer which regulates the vacuum going to the control head and the power servo.
Lets see what issue comes up next spring…

edge
The Rheostat when set to the lowest temperature setting shows around 2,5 Ω You can check if it is working with an Ohmmeter.edge
At the highest temperature setting the resistance is getting lower.edge
The Amplifier part of the control head is on the underside. Something in here must have gone bad on my control head. I will try to find out what went bad and repair it to have a spare part.

The 67 Eldorado is back on the road for the 2015 season.

1967 CADILLAC BORG CLOCKS REPAIR AND A PROBLEM WITH A PRINTED CIRCUIT BOARD.


edge
The 1967/1968 Cadillac Westclox clock out of my 67 Eldorado.


The last time I tried to repair the clock in my 67 Cadillac DeVille I totally failed. This was in 1998…
After I got the clocks in all the other Cadillacs moving again - I could no longer stand watching the dead clocks in my 67 Eldorado and DeVille.
So I decided to try to repair them as well.
The last repair attempt at my 67 Eldorado was very disappointing.

In 1998 I took the clock out of my 67 DeVille the last time, and after my repair attempt the hands started spinning in an extremely fast pace - like a ventilator. So I had to disconnect the power to the clock at the printed circuit at the back of the instrument cluster. When I did that I forgot to disconnect the battery and when the power feed touched some metal I had a short somewhere and some smoke came out of the dash… I could not locate where the smoke was coming from - all wires looked perfect. So I just insulated the clock coil power feed and gave up on the repair and forgot about what had happened.
As I found out now - some connection of the printed circuit board got burned back then…

After the failed repair of the 67 Eldorados clock last fall, I decided to try to find a good used clock. Once again Arizona Vintage Parts - my favorite source for parts - came to the rescue. He sold me two non working Borg clocks for a really good price. Unfortunately by now he has run out of stock for them.

So I tried to repair the clocks he sent me - appearance wise they were in very good condition, and I got one back to life for a short time by just cleaning it.
So I put it back into the car and then I made a stupid mistake and ruined it completely. I wanted to tighten the mounting screws and accidentally grabbed the connector for the coil - as you have to work inside the dash without being able to see what you are doing - and so I overtightened it… This stripped the threads of the coil… I had to cut the nut off then and somehow the oscillator wheel inside the mechanism did no longer work properly and when I tried to adjust the stepper it broke off :-(
BTW - Do not use WD40 for cleaning and lubricating a clock like I did… This will ruin the clock as I found out when it was already too late… There are special clock oils available to lubricate clocks.

The other clock I got had a defective oscillator wheel and I could not repair it as well…
So I contacted Arizona Vintage Parts once again for some new clocks but he had sold all his stock on clocks to Sweden…

I had to contact all the Cadillac Parts dealers I found in Hemmings Motor News for two Borg clocks, but I was unsuccessful or they were exorbitantly expensive. Some of the well known Cadillac Parts dealers either did not have them, did not react to my inquiries or asked up to $ 385.- for a used, rebuilt clock. Others asked up to $180.- for a non working clock.

Luckily I found a company called “The Clockworks" which was highly recommended on some Cadillac and other classic car forums for their good work in repairing clocks and also converting them to a quartz movement.
Everybody seems to recommend to convert your clock to a much more reliable and cheaper quartz movement. I thought about it for a while but I decided that I wanted to go for an original movement for authenticity reasons. If you convert to quartz the "tic-toc" movement will be gone and you can tell by just looking at the clock…

I ordered two rebuilt Borg clock movements for my clocks from "The Clockworks". Their service was excellent and they were a great help. Great customer service! I would buy from them again or have my clocks rebuilt by them anytime.

After I received the movements I installed them and put everything back together. You have the keep the adjustment stem and the housing from your old clocks if you replace the movement.
When I put the clock back into the 67 DeVille it did not work though. I soon found out that no power was coming to the coil through the printed circuit board.
I then remembered about my failed repair attempt 17 years ago and the smoke that came out of the dash… Somewhere the circuit board was burned. So I connected the orange cable going into the multiple terminal connector at #7 terminal to the clock directly and it worked again.
So I installed a cable directly to the clock. This is a temporary fix until I´ll have a new circuit board. Installing a new board requires to take the dash completely apart to replace it.

A printed circuit board is available new here: https://www.opgi.com/cadillac/CE11091/

1967 AND 1968 CADILLAC ELDORADO HEADLIGHT ACTUATOR REPAIR ARTICLE UPDATED

One of the most read articles on my website is about how to repair the somewhat troublesome headlight actuators on the 1967 and 1968 Cadillac Eldorado.
After many years they tend to fail for many owners of the 1967 and 1968 Eldorados.
One company has offered a reproduction, but from the experience some people made with it, it was said that it was very poorly made and extremely expensive. I can´t tell anything about it from my own experience though.

But there is a better and much cheaper solution to the problem in the form of a modified reproduction 1969 Camaro RS actuator which is readily available. I´ve written an article a couple of years ago what could be done and I have now updated it, as one reader sent me some excellent description and pictures of how he modified the Camaro actuator to work perfectly on his 1968 Eldorado.
Thanks for the tip Mark Maromonte from Marks Truck and Auto Repair.

REPAIRING THE CLOCKS OF THE 1958, 1966 AND 1967 CADILLAC

I like it when everything works on all cars.
So it was time to service some of the clocks which stopped working over the years.
The clock in the 66 did not work at all.
It's extremely simple to remove on the 66 as you can get it out of the instrument panel by just unscrewing one bolt.
The clock was very dirty in the clock work and needed a good cleaning and some good lubrication. Also the contact of the coil was a little worn and this was fixed. It then happily ticked back to life and now works perfectly.

The clock on my 58 stopped working a couple of years ago. So it came out as well. It's a little more complicated to get it out though...
When it was finally out - it could be seen that the coil was burnt and that it needed some very good cleaning as well. Some of the melted insulation material was all over the clock mechanism and of course I had no spare coil for it - so the original one had to be rewound with some good wire from a left over light solenoid...
Wow - this really took a while - but now the clock works perfectly again!

I was not so lucky with the clock on the 67 Eldorado which only worked when the car was warm. To take it out you have to remove the upper dash and then get out some light bulbs and disconnect it from the printed circuit.
It was also cleaned and lubricated and the clock worked, but it made a very loud noise when the coil rewound the spring of the clock.
The sound got better over night, but then the clock stopped working completely... It's a Westcox clock which uses a double coil and is much more complicated to rebuild than the Borg clocks. Its also almost impossible to find parts for it, as Borg clocks are much more widely used.
Looks like I will need a new 1967 clock and replace it with a Borg unit :-(

1967 Eldorado headlights did not work

As we had a very nice evening I wanted to take the 67 Eldorado for a spin.
When I took the car out of the garage I noticed that the headlights did not come on, but the taillights worked.

I suspected that the light switch must be the problem... I unplugged the connector of the switch and tested if 12V power was coming to the switch through the wiring.
There was one hot wire and I connected it directly to the headlights and they came on.

I then wrongfully assumed that the switch must be the problem then...
So I decided to take it out and inspect it.

Getting this switch out is a real pain as there is one screw thats almost impossible to reach. You can only get to the switch from underneath the dash btw...
It took me a couple of hours to get it out lying on my back under the dash...

I then opened up the switch and when I opened it up it fell apart immediately. I had a really hard time getting it back together correctly. Before that I cleaned everything inside.
I measured it with the multimeter and everything was fine.
Getting the switch back into the car was even more difficult than taking it out... There is this one d*mn screw thats almost impossible to get back in. Try to avoid to take the switch out, as you can measure if it works with the multimeter. I did not read the electrical diagrams carefully enough, so I did not measure it correctly and so I took it out.

!!! Be aware that the headlight switch on the 67 Eldorado is almost impossible to find, as it is a very special switch with the vacuum valves! If yours has twilight or auto dimming its even harder to come by!!!

As it turned out my switch was o.k. and the headlights did not work for another unknown reason... So I googled the problem and to my surprise I found my own website with a solution!
I had completely forgotten that I had the very same problem with my headlights a couple of years before and found a solution back then. I was just lucky that I do use my website as a sort of diary for the repairs I do on my cars.

As it turned out the same fusible link had burned through again. It runs very closely to the headers to the starter on the positive battery cable. Maybe it got too hot and failed or just broke apart. I could not see any melting or signs that it had burned through. It looked fully intact from the outside and I could only see that it was defective when I removed the insulation...

To replace the fusible link you have to take out the positive battery cable and replace the fusible link. Thats not a big deal. I rerouted the cables a little bit this time and hope that it wont fail again.

My 1967 Eldorado Article in the German Cadillac Club Magazine.

The Classic Cadillac Club of Germany asked me if they could use the history of the 1967 Eldorado which I wrote for my website as an article for their club magazine "Der Standard" along with a couple of images I took of my 67 Eldorado. I felt honored and Christian Doerk made a nice 9 page article for the magazine out of my pictures and my text.
The Cadillac Club of Finland will also feature this article in one of their next club magazines.

1967 Eldorado with only 8.000 miles for sale!


UPDATE: !!SOLD!! - IT SOLD VERY QUICKLY!


I´ll leave the description below just to let you know what you have missed ;-) Congratulations to the new owner!



This is your chance to own one of the lowest mileage 1967 Cadillac Eldorados on the planet!
Up for sale is a breathtaking 1967 Cadillac Eldorado with less than 9.000 miles on the clock. It's an all original car and probably one of the best in existence.
The car is located in Florida and was brought back to life during the last year. Its for sale by the second owner of the car who owns it for 25 years now and wants to let it go due to his age and as he has nobody to pass this car on.

The original owner died when the car had 7800 miles on it. The car was stored in a heated garage until a broker purchased it. It was then purchased from him by the current owner. It was only driven to local shows. The car is as straight as an arrow. The only repaints on the car are the air cleaner and the valve covers, every thing else is original. This car has drum brakes all around, which can be a plus since rotors are not available.
This car has not seen rain in the last 25 years. Since there is no rust on the drums, I wonder if this car has ever seen any rain.
A list all the things done to the car:
  • Radiator boiled out and pressure checked.
  • Carb rebuild.
  • Brakes rebuilt.
  • The vacuum switch for the air conditioner was replaced,
  • It has the original Freon in it and comes with 1 and a half cans of the original Freon that goes with the car.
  • The water pump has been replaced.
  • the vacuum motors that operate the headlight doors were replaced. All the vacuum lines for this have been replaced as well.
  • The vacuum lines for the leveling system have been replaced and the system worked fine except that one shock leaked and both rear shocks had to be replaced. The replacement shocks have a spring with them and the car sits perfectly and handles great. The old shocks will go with the car in case they can be rebuilt. Vacuum has been blocked from the pump so it does not run all the time.
  • The complete muffler system has been replaced with original parts.
  • The original tires have been replaced except the spare witch has never been removed from the trunk.
  • The interior is in mint condition.
  • The chrome and stainless are really nice, except for one spot on the front bumper, which I think a hot lead hit the bumper years ago. You can see it if you look at the picture of the passenger side bumper pic. Its not that bad but its there. To fix it would require a re-chrome.

As this is a very special quality car it won't go cheap of course! This is one of the best 1967 Cadillac Eldorados in the world.
If you are seriously interested - let me know and I can put you in contact with the seller! If I had the money to purchase another car, I would definitely buy it for myself!

Bleeding brakes and spring cleaning

Finally we had some warm weather and it was time to start working on my cars again.
First up was the 1958 Cadillac Eldorado Seville which needed new brake fluid.

So I sucked out the old fluid from the reservoir and flushed all the lines with fresh DOT 3 brake fluid.
I started at the right rear line, the left rear, the right front and left front brake cylinder.
Although I have a pit its still a pain to reach all the bleeding screws. The power brake cylinder itself also needs some good bleeding.
Thanks to my dear wife Afra for gently pumping the brake pedal and helping me out.
When you bleed brakes make sure your assistant does not push the brake pedal all the way through as this could damage your master cylinders membrane.

Next up was a thorough cleaning of the garage floor.
My 3 year old son Elliot also wanted to help his daddy and helped me swiping the floor ;-)

Outlook to the 2012 season - doing the first repairs 2012

As we had a nice sunny, dry winter day today I decided to re-arrange the cars in my garage so that I can start doing some work on them during the remaining cold winter nights.

The following work is planed for the next few months before the cars will be put back on the road in May 2012.

1971 Mark III


1967 DeVille

  • needs new front wheel bearings (I already have the spare parts)
  • will try to find a rebuilt OEM Bendix master cylinder and vacuum booster. These are very difficult to find. Everybody seems to offer Delco Moraine parts only. I have replaced my original booster and master cylinder 2 years ago and I´m not quite happy with the power assist of the new units. It seems that the after market master cylinders from Delco have a smaller bore diameter and therefore you will have to depress the pedal with more force. There is a discussion going on on the topic of finding the correct booster and master cylinder in the CLC forum - check it out for more detail! If you know where I could find a correct Bendix booster and master cylinder or where I could get my original core rebuilt, please let me know!! The parts number for the Bendix Master Cylinder is #1489981 and for the Bendix booster it is: #1489071
  • re-adjust the gear indicator as it's slightly out of line.

1967 Eldorado

  • I will remove the starter motor and have it rebuilt - it sometimes is acting up

1958 Eldorado

  • It needs some new front wheel bearings as well. I already bought the parts.

I will of course post the repair progress here on my website

A new garage?


The biggest planned project for 2012 will be to find a solution for my storage problem. I hope to be able to build another garage or to rent one. I will have to find a solution until the spring of 2012. I´m dreaming of building a building which can hold 8 Cadillacs, but I do not know yet if I will be able to afford it...

Car Shows


I hope to attend and visit the „Klassikwelt Bodensee“ from May 17th to 20th and of course the best meeting in Europe - the Cadillac BIG Meet August 25th to 26th. I will also hopefully make it to some local shows here in Austria.

The cars are in winter storage :-(

With winter approaching rapidly, today I returned the license plates of my cars and put them into winter hibernation. I did not drive my cars very much this summer due to a mostly very rainy summer. So I did not rack up too many miles on my cars this season. I just made about 200 - 400 miles on most of them...
The cars are now in their cosy garages and will all get a new wax-, lubrication- and thorough cleaning job during the next few weeks. I usually also disconnect all the batteries, give the weatherstripping and rubber a good coat of silicone spray and treat all leather areas with leather conditioner. I also clean the interior carefully and over-inflate the tires to make sure that they do not get any flat spots. I will also park the tires on styrofoam. I really hate winter and snow and I am already looking forward to next spring... Over the winter I will rebuild the starter motor of my 1967 Eldorado and detail the undercarriage. The Lincolns undercarriage will get a very good cleaning as well. The 67 DeVille will get some new front wheel bearings and probably a new wheel cylinder and power booster. The 58 Eldorado will also need new front wheel bearings. So there will be a lot of minor things that will keep me busy over the winter...

Below are some pictures of our very last cruising tour this week with the Mark III

Mostkost Kustom Show 2011 and Sepp's Garage

Today my little family, together with our best friends, visited a nice small meeting which is held only 40 kilometers from our home. Its a small gathering of US-Car enthusiasts. One of the organizers is collecting and building great Ratrods which he is always showing there. It's a very nice and relaxed atmosphere with nice cars and great people. Looking forward to the next edition. Sepp also gave us a tour through his fantastic garage and collection of super rare speed parts. This guy is unbelievable!
We took the 67 Eldorado to the show.
My wife and I shot lots of great images which are available in this gallery.

The 67 Eldorados new POA valve and recharge of the AC

The Eldorado leaked all of its refrigerant charge over the winter, so it was time to bring it back to the shop. It was recharged with R134 and all the necessary changes were made for the conversion.
I got a new remanufactured POA valve (suction throttling valve) from Classic Auto Air to make sure that the system can cope with the much higher pressures of R134. Classic Auto Air was very helpful with providing the factory correct parts. Classic Auto Air says that the re-calibrated valve can make a 15-20º F / 6º C difference.
Yesterday I got the Eldo back from the shop and so far it seems to cool the car down properly. The air discharged out of the vents is 10º C / 50º F cold - not bad for R134.

This is what Classic Auto Air is recommending for a change from R12 to R134:

Minimum Requirements

  • Change or restore the filter-drier.
  • Drain the compressor oil and recharge with 134a compatible oil. (PAG or Ester Oil)
  • Insure that the system is clean and free of contaminants (Depending on component condition, this may be a simple matter of blowing out with compressed air or liquid flushing with an air-conditioning flushing agent)
  • Replace or restore all rubber hoses with barrier hose.
  • Install 134a charge port adapters
  • Send POA valve in to be calibrated
  • Charge with 134a between 70-80% of the original R12 charge amount.
  • Replace any o-rings with 134a compatible

Recommended:

  • Install hi/lo pressure switch

HELPFUL HINTS

  • Ignore the sight-glass. A properly charged 134a system will likely show bubbles in the sight-glass.
  • Typical 134a charge rate will be approximately 70-80% of the factory R12 charge amount.

edge
The new factory correct POA valve. Internally it was calibrated for the use of R134 instead of R12. The expansion valve was also replaced together with the evaporator, condenser, compressor, O-rings, filter-dryer. I did not install a hi/lo pressure switch which would cycle the compressor on and off to keep the car original.

THE 1967 CADILLAC AUTOMATIC CLIMATE CONTROL SYSTEM - MORE ISSUES - AND A FINAL FIX? RESTORING THE POWER SERVO VALVE!

When I took my 1967 Eldorado and my Deville out of winter storage and tried everything, I ran into some problems with the Automatic Climate Control once again. (see this post with vacuum diagrams and also this posting about my blower issue and this post)
The 67 Eldorado lost its complete charge of refrigerant over the winter - so it will have to go back to the shop to see where it is leaking. All components were replaced with new ones last year and so I have no idea where it could have leaked out. A tracer was put in before the last recharge so we should be able to find the leak. I guess that it will be one of the original hoses are a bad fitting.

Another thing that bothered me was that the system basically worked most of the time, but sometimes I had to wait for a long time before the system came on, or I had to switch to “FOG“ or “ICE“ position before the blower would come on in the “Auto“ position. Then sometimes the blower would cut out again if the temperature dial was moved to a colder temperature. Sometimes the temperature would move to full heat regardless off the selected temperature in the 67 Eldorado.
I had the very same problems on my 67 Deville as well - but there also the “Vent“ and “Low“ position did not work at all...

So I started trying to find the issues and finally wanted to fix them. Sounded easy - but it took me 4 full days with long nights in the garage to fix it...
BTW - Cadillactim has an excellent trouble shooting guide for the ACC on his website - its for sale for $ 45.- and I can highly recommend it if you are troubleshooting your 1967 or 1968 Air Condition System.
A great troubleshooting guide for 1967 and 1968 Cadillac´s Automatic Climate Control Systems I got from Gary Sisk - owner of a 1968 Cadillac.
This is a very easy to follow explanation which will save you a lot of time and you do not even need any special tools.
It was written by Lynn Nicholls and can be found on Stampies Cadillac page - here is the direct link to it. I used some excerpts from his document in the explanation below:

I first suspected a vacuum leak to be responsible for most of the erratic behavior of the system. A clear indication was that the system would initially have to be switched to the “ICE“ position to make the blower come on.

Lynn Nicholls writes:

“Sometimes the dash control can be switched to the fog or ice positions to bring the blower motor on and then when it is switched back to auto the blower may stay on and the system seems to work fine until the car is shut off. If the vacuum leak is only moderate there may be enough vacuum to hold the master switch closed once it gets , but not enough to pull it closed in the first place. When the dash control is switched to fog or ice, it assumes the air temperature is cold and that the engine is not yet warmed up, but that the blower is needed immediately for defrosting the windshield. So it supplies vacuum to the master switch through another circuit, bypassing the temperature controlled vacuum switch on the heater core shutoff valve on the right fender well. This source of vacuum is enough to close the master switch.When the dash control is switched back to auto this vacuum source is shut off, but there may be just enough vacuum left from other circuits to hold the switch closed. This routine will work for a while but as the leak gets worse, there won’t be enough vacuum left to hold the master switch closed anymore and the blower will shut off again as soon as the system is switched back to auto.With these symptoms and behavior the problem is most likely the power servo. This is half the brains of the system; the other half is the control panel in the dash. The power servo is controlled by a varying vacuum signal from the transducer. This vacuum supply is a completely separate circuit from that which supplies vacuum to the master switch. High vacuum moves the servo to the maximum heater position, and with low vacuum, a return spring moves it to the maximum AC position. In between these two extremes, it regulates the air temperature door to blend warm air and cool air, and simultaneously regulates the blower speed. It also spins an internal rotary vacuum valve back and forth that makes various connections between the several small vacuum lines on the top. This rotary valve controls the various vacuum motors of the system that operate the AC, heater, and defrost functions. It is this rotary valve that goes bad. l have seen these things visibly warped, and very badly so. It must be caused by engine heat, because there is also one inside the car on the control panel that is moved back and forth by the dash control lever, but that one seldom seems to cause any trouble. A warped rotary valve leaks all kinds of vacuum and the first part of the system to be affected by low vacuum is the master switch; there’s not enough vacuum there to close it and turn on the blower. To verify this is the problem, take some spare vacuum line, some scraps of 1/8 inch pressure line (like for air shocks), and a vacuum T and manually make the connections that the rotary valve should make in the maximum AC position. The connections that the rotary valve makes in various positions are shown in the factory shop manual. Disconnect the black connector with the striped vacuum lines from the power servo. Connect the yellow, red, and purple lines together with a T; also connect the tan and blue lines together and connect the orange and green lines together. If this rotary valve is the one and only culprit the AC will now work beautifully and the blower motor will come on every time, like magic. With the dash control on high the system should be recirculating air and there will be a lot of air noise coming from under the right side of the dash; when the dash control is moved to auto the air door should move to provide fresh air and the system will become much quieter. Of course with these manual connections the system is not fully automatic and the heater won’t work right at all, however this is enough to diagnose the problem.“


I did this test (see picture below) - and with the power servo bypassed everything worked as it should. This way I knew that the power servo was to blame for some of my problems.


powerservo-BG_MG_3866_HDR
So this rotary valve needed to be repaired...
powerservo-BG_MG_3867
I removed it from the power servo and disassembled everything.

After opening the cover, you can see the rotary valve in the lower center.

powerservo-BG_MG_3879
The rotary valve consists of two halves which make the connections - as you can see it was very dirty and rough - and slightly warped.

powerservo-BG_MG_3880
I started to wet sand both halves with 800 grit sandpaper.

powerservo-BG_MG_3882
When everything was flat and shiny again I used some 2000 grit sandpaper for a perfect finish.

powerservo-BG_MG_3886
Looks shiny and flat again

powerservo-BG_MG_3889
Make sure that none of the ports are clogged - I used compressed air to clean everything.

When you put the two halves together lubricate with WD40 to make sure that when you put them back into the power servo that they are properly held together with the underlying spring.
After I reinstalled them into my cars - almost everything worked as it should. In the 67 Eldorado I still had the problem that in the “AUTO“ position the fan would always be slow - so I knew that the control head in the dash had a problem with the “LOW - AUTO“ switch as well.
In the 67 DeVille the “VENT“ and “LOW“ position still did not work at all...
So I switched the control panels between the two cars and suddenly everything in the 67 Eldorado worked perfectly. I never had such a perfectly working system before. Its like it just left the factory!
In the DeVille I still had no “VENT“ and “LOW“ settings working... So out came the control panels again... (its a pain in the a*** to remove and install them...)
As it turned out the “LOW-AUTO“ switch on one panel was stuck in the “LOW“ position. You can easily remove it and readjust it to work again - sorry I forgot to take pictures. Make sure that all switches on the control head are adjusted properly or they wont work as they should!
So I knew that both control heads were working correctly by installing it back to the 67 Eldorado and the other panel back to the 67 DeVille.

While the 67 Eldorado was perfectly fixed now with everything working as it should - the 67 DeVille was still giving me the problem with a non working “VENT“ position...
I studied the shop manual for hours and could not find what the problem could be. I knew that the power servo was working perfectly now and I knew that the control head was in perfectly working order as well. I verified this once again by switching these parts between the cars once again and everything worked as it should in the Eldorado but not in the DeVille.. I´m really good in switching these parts between my cars now ;-)

I started to look for electric connection problems and finally found out that no electricity was coming out of one of the three power servo connectors, but I did not know why...
After I removed the power servo once again to re-check it again it struck me - one of the pins was slightly bent and the wire connector did not make proper contact. This problem was not visible with the power servo installed in the car. It took me 2 long nights to find this little flaw... I just bent it straight and everything works as it should on both of my 67 Cadillacs. Now I have to recharge the systems and I should have perfectly working AC again... I will also install new dryers and a re-calibrated R134 POA valve before the recharge.
One the one hand the 1967 ACC is very complicated but once you know how it works its pretty easy to fix. The rotary valve in the power servo is pretty easy to refurbish, the dash servo valve is riveted together unfortunately, so its not such an easy fix, but NOS valves are still available at “Classic Auto Air“
*UPDATE 2022* - Check out this article and video as well as I had to repair my switch again in 2022 on my 66 DeVille!

Good morning Cadillacs!

Spring is around the corner and so it was time to go down to the garage and wake up the Cadillacs from winter hibernation. I put them into storage in October last year over the winter. In May I will get my license plates again and I can start driving them for this season.
Before the season actually starts I started to prepare the cars. I checked all fluids, checked the tire pressure, reconnected the freshly charges batteries, pushed the cars out of the garage, pumped the pedal a couple of times and then cranked the engine. One after the other came back to life. Great! I took them for a quick drive around the house and checked all systems.
I´m now starting to clean each one and give them a thick coat of fresh Meguiars wax. The leather seats will also get another treatment with Gliptone leather conditioner. I thoroughly cleaned the cars before I put them into storage and also changed the oil before I tucked them away, so there is not that much to do at the beginning of the new season. I have two more weeks now before I can officially drive the cars again - this should be enough time to make them look absolutely pristine.

1967 Eldorado with Sunroof from ASC

A 1967 Eldorado with sunroof?

A while ago I was contacted by fellow 67 Eldorado owner Mark Bristol. He owns a very rare 1967 Eldorado with a sunroof done by ASC (American Sunroof Company). He asked me if I knew anything about it.

I had never heard anything about a sunroof in a 1967 Eldorado unfortunately, and so I could not help him out with any kind of information.

So Mark Bristol did a lot of great investigation work and found out the following:

“ I have found quite a bit out from my research.  I spoke with Christian Prechter, President owner of ASC West on the phone.  He was brought over from Germany when he was 19 in 1966 to help his brother Heinz Prechter do installs at the ASC West location and stayed there doing custom installs when ASC opened the Southgate Factory in Michigan.  He told me that he did over 50 1967 Eldorados that year for various Stars and VIPS.  He recalled doing mine for William Morris and even told me what color it was without me volunteering it to him.  He said it was the only Marina Blue one he did!  I quizzed him several times in a cross examination method to make sure he was not just telling me what he thought I wanted to hear.  He said he is 100% certain he did it personally as he was actually doing the installs himself back then.  The conversation went like this:  „Hi I am Mark Bristol from Tomball, TX sorry to bother you at your home residence.  I have a 1967 Eldorado with a sunroof.Did you ever install any sunroofs in 1967 in Eldorados?“.  Prechter, " I installed over 50 for people like Sinatra, Dean Martin, Sammy Davis Jr. and William Morris.“ „Wow that many?“  Prechter "Yes it was very popular that year."  „The car I have was William Morris' car do you recall doing it?“Prechter, "I sure do it was the only Blue one I did that year"  „So you did a Marina Blue one for William Morris.  That was a long time ago and you remember specifically doing this car, that is incredible are you sure?“  Prechter "I am 100% certain I did it"  „So your division didn't get sold off to Inalfa.“  Prechter "Yes, I kept the custom install portion ASC West as it is the most profitable segment."„How involved are you with the actual operation of the company?“  Prechter  "ASC West is still doing custom installs daily and I personally over see the operation." „Christian,  Thank you for your time, you have been very helpful in understanding how these sunroof Eldorados came to be.“ It was a fairly short conversation I'd say 3-5 minutes with a very revealing content.  I intend to mail him a packet with a photograph of "Elle" to autograph and several pictures to review and a certificate of authenticity for him to sign.  Hopefully he will take the few minutes it will take and return it to me in the mail. A former President of the Cadillac Lasalle Club lives here in Tomball.  He was president from 2004-2008.  He stated he has seen 2 sunroof cars in person mine would make number 3.  So they are floating around out there somewhere 50+ of them.   My rule of thumb is 10% left in any condition after 40 years. That would mean there are 2 more out there some where!!!“ Mark Bristol

The 67 Eldorado now has a working radio!

Today I spent the first day in the garage in 2011. Spring is around the corner and temperatures are going up slightly. Over the winter I collected some parts for the 1967 Eldorado and now it was time to install them.
Up first was the radio. The Eldorado came with the original AM radio. When it was turned on nothing happened though... The power antenna worked flawlessly and the signal seeking feature worked as well, but it would not make any sound at all. So I assumed that the speakers were shot and got a new front and rear speaker from Greg Thompson from Turnswitch. They have exactly the same size as the original ones. Cadillac used 10 Ohm speakers for all their cars in 1967. I installed them today and the radio came back to life. As there are no AM stations around any longer I came across a great solution which would enable me to use an Ipod or Iphone to play over the original radio, without having to do any non original conversions to my car. Its a plug and play solution which can be undone in 2 minutes and does not involve any cutting or screwing. The product is called RediRad and it works perfectly. Just tune the radio to 1000 khz on the AM band and plug in the audio source and you can hear your favorite music on your original radio! It is simple and affordable and undetectable as its hidden under the dash.

I also tried to repair the broken stem on my clock and it took me a while to get the clock out only to find out that my replacement stem would not fit. So I had to reinstall it. But at least it seems that it has a better electrical connection to the printed circuit now and the clock works all the time now. Problem is that I can only set the time with long nose pliers at the moment. Looks like I will need an entire new clock or live with it the way it is now. At least it works...

It was great to spend some time with the car again after the long winter months!

The 67 Eldorado is at the shop again

Finally my climate compressor showed up from the USA. The USPS kind of lost it and it took three months to arrive at my door... In the meantime I had ordered another one because it was thought to be lost and so I ended up with 2 climate compressors for the Eldorado. The old one was leaking its charge and so I decided to go with a new rebuilt one.
Also the ignition and the rebuilt carburetor were not quite up to my standards yet, and so I decided to ask for some professional help for the last finishing touches. So I delivered the car to the shop, and the experts did some more tweaking. The result is that I finally have a perfectly working AC on my car. It took a while, but finally it's working as it should. When I got the car, a lot of AC parts were defective or torn out, and now everything is back to factory specs.
Also the carburetor is finally working as it should.
From a technical standpoint the car is now in perfect condition - you wont find anything that´s not working as it should.
Great! - next up is a repaint...

Detailing the paint of the 1967 Eldorado

My buddy Tayfun was in town for a visit and we spent quite some time in the garage detailing the paint of my 1967 Eldorado. We used a lot of Meguiars products for a mirror smooth surface. The original paint is much shinier and glossier now and looks pretty good. Thanks for your help Tayfun !!!!

A photoshooting with the 1967 Eldorado

As we are having an extremely rainy spring and summer here in Austria at the moment, my wife and I used one of the very few sunny evenings so far to go for a photoshooting with the 1967 Eldorado.
Afra used her old trusty Hasselblad camera which, even in the digital area, is better than any new camera, and shot a roll of good old black and white film and another roll of color slide film. She now scanned the films and the results can be seen here!

1967 Eldorado Headlight Actuator repaired

After my last repairs at the car, the right headlight door did no longer close properly. Only if I wiggled on the vacuum hose on the actuator which is responsible for opening the door (the green hose), the door would eventually close. So I thought that the actuator was shot and I ordered one from a 1969 Camaro RS which looks almost identical with the only difference being the rod ends which are completely different on the Camaro. The original mounting pins on the Eldorado are screwed on and can be removed pretty easily from the rod, which has a thread on the end. On the Camaro actuators, the rod end is pressed in place and the rod has no thread at all... So one would have to find a way to switch the rod ends and modify the reproduction actuators...

The instructions on the reproduction part mentioned that one could use silicone spray to lube the internals of the actuator through the vacuum inlets - this would also make the rubber parts in there soft for a better sealing. So I thought it might be a good idea to spray something in my old part and really soak it...
I had the impression that the rod was easier to move after application. I also put some gasket sealant around the vacuum inlets, just to make sure that there is no leak anywhere.
So I installed the old unit once again and it still did not work properly - but it worked fine if I only installed one vacuum line at a time. Suddenly it rang a bell. There are some T-connectors which also act as a valve going to each actuator. They do vent the system on one side when the doors are operated.
I cleaned the connector valve and reinstalled one hose going there and suddenly everything was back in working order! It now works like it should again!
Looks like I bought the new actuator for nothing... It cant hurt to have a spare though, as they are pretty fragile and even failed when new in 1967... In the meantime I might also find a way to install the original rod ends... Let me know if you have an idea!

If you are looking for a vacuum diagram for the Eldorados headlight doors you can find it on my website.

The different rod ends - the original one on the left - the headlight door mechanism is installed in the center of the rod end with a pin.
On the Camaro unit one could probably install it on the side using a bushing.
I have heard that this worked fine for some Eldorado owners as you can see on the picture below.

edge
This is how it worked for another Eldorado owner - he installed some bushings on the new unit.
I found this picture on ebay at the auction for a 1967 Eldorado recently.


Update November 2014:


I have been in contact with Mark Maromonte who found this post on my website and replaced his bad OEM actuator with the 69 Camaro RS unit. He did some modifications and sent me some pictures to share here. Thanks Mark! I´m sure its helpful to others as well:
Mark wrote (all pictures below were provided by © Mark Maromonte):

I bought an actuator for a 1969 Camaro  RS. I removed the two pins that held the attachment to the end of the rod. Then I cut 3/8 of a inch of the rod off, so the rods were the same length. Then I beveled the end of the rod on a grinding wheel, for about a ½ inch at the end of the rod. This was done so that I could start a ¼ tap on the end of the rod. After the tap was done. I threaded on the Eldo clevis pin. Done! 20 minuets, $76 vs $245. Works fine. Thanks again for suggesting that in your post. Take care, Mark

The 1969 Camaro RS headlight actuator is slightly different from the original Cadillac actuator. It can be made to fit though.

A problem with the 67 Eldorados carburetor

I brought my 67 Eldorado home from the restoration shop yesterday only to find out that the AC compressor died and leaked the fresh refill it got. Everything is new except the compressor and of course it died at the first usage. The system was pressure tested at the shop and worked like a charm. When they let the car idle with the AC on, the compressor started to leak. They tried to fix it but had no success. So I will need a new compressor and a new charge.
The right headlight door actuator also suddenly no longer works correctly. All hoses are new and it worked perfectly until recently. I can now only make it close if I jiggle on the actuator. Is there any way to rebuild them? A source for new or rebuilt ones? I have heard that the ones from the 1969 Camaro is very similar and only needs some minor modifications to work on the Eldorado as well. So I went ahead and ordered one. But the worst thing was that the freshly rebuilt carburetor made strange ticking noises and sounded like a tractor while accelerating. It worked well though, but the sound was unbearable. Could it be a defective gasket? It was also idling quite badly. Acceleration was superb though, its much more powerful than before, but still something was wrong... The ignition also was completely rebuilt. So I played around with the ignition first, but the ticking sound did not go away, no matter in which direction I changed the timing... Almost sounded like an exhaust leak, but there seemed to be none... It was LOUD! Before I had the carb and ignition rebuilt, it was extremely quiet and idling smoothly but had misses while accelerating.
I got some very valuable tips from fellow Cadillac aficionados and the previous owner of this Eldorado even called me from the USA to give me some tips to solve this issue, and he was spot on with his diagnosis...

With a hose held to my ear and the other end to the carburetor, I was able to locate the source of the noise. It came from the carburetor below the choke assembly. So I took the freshly rebuilt Rochester Quadrajet out again, only to find out that the gasket and the metal shim were installed the wrong way around. This burned a hole into the brand new gasket where the exhaust gases from the heat crossover passage could escape and make this noise.
Of course I did not have a new gasket at hand, so I carefully removed the old one from my spare engine, which was in pretty good shape and installed it.
No more ticking - no more noises, no more bad idling.
The car now drives amazingly good and is silky smooth. It could not be any better.

The shim was installed first and then the carb - thats wrong! The gasket has to go on the intake manifold first - then comes the metal shim.

The 67 Eldorado is at the restoration shop again

Yesterday the 67 Eldorado was picked up by the restoration shop. As some bolts broke off when I tried to repair my waterpump issue, and I do not have the necessary tools and skills to deal with broken bolts, he came by and picked the car up. He and his team will fix that for me hopefully soon.
Also on the „to do list“ is to install a new condenser for the air condition, recharge it with good old R12 and to fix a problem with the ignition timing. Cant wait to have the car back!

The 67 Eldorado´s waterpump is defective

When I repaired the seat transmission of my 67 Eldorado I drove the car out of the garage to have more room. When I wanted to drive it back into the garage, suddenly the radiator boiled over and the temperature gage showed full heat. I immediately shut down the engine. The car never had an overheating problem before and the radiator is new as well.

There are only very few possibilities why this could have happened.

  • The thermostat did no longer open
  • The waterpump failed
  • Air was trapped somewhere in the cooling system

So I removed the thermostat housing first to check the thermostat. This is when disaster struck. The two bolts in the thermostat housing snapped off immediately when I tried to unscrew them. *Cr*p”
I then removed the thermostat and put it into boiling water and it worked perfectly. So I think I can rule out the thermostat.
As the upper radiator hose stayed pretty cool and it did not feel like there is any coolant circulating through it, I suspected the water pump. Maybe the impeller does no longer work. I will have to remove the pump to check it.
My friend Richard came over to help me to try removing the broken bolts which got stuck in the cylinder head water outlet pipe. As all methods we tried to remove the broken bolts failed, we began drilling the remains out. This did not turn out very successful either... The threads also got damaged with this method. Of course one could now rethread this part, but I decided to order a good used one.

Once again Arizona Vintage Parts is the company where I ordered all the spare parts. They are really a great company! They are reasonably priced and so far they had everything I ever needed and inquired for. They are a pleasure to deal with and I can highly recommend them. I´m looking forward for the parts to arrive, as the car in its current state is immobile and blocking the garage...

UPDATE 03/09: The parts from Arizona Vintage parts already arrived within a couple of days after ordering! Wow thats fast! Now I need some time and warmer temperatures to install them...

Normally the thermostat is in there. You can see the mounting holes from where we drilled out the bolts. Unfortunately the threads did not survive this treatment...

1967 Eldorado Seat Transmission repaired

When I got my Eldorado one function of the 6 way power seat did not work. The rear tilt function did not work at all and was stuck. When I pushed the according switch I could hear the motor spin but nothing happened. So I crawled under the seat and saw that the according transmission wire was disconnected from the actuator. I reconnected it but this did not change anything. I then checked all the connectors for current. Everything was o.k. there, so it could have only been the seat transmission itself.
I removed it from under the seat, what was a little tricky and involved getting in some strange positions to access all the screws. It would be easier if one removes the seat from the car, but thats a rather unpleasant work as well...
Eventually it came out of the car. I disassembled it and at first everything looked pretty good, but it soon showed that the old grease became rather hard and sticky and one of the three solenoids was no longer able to push the gear into a locked position.
I thoroughly removed all of the old grease and re-greased everything with white lithium grease. I then reassembled everything, reconnected the gear cables, reinstalled the transmission under the seat (thats a very tricky part...) and everything worked like new!
I now have perfectly working power seats again!

1967 Eldorado Door Jamb Switch Repair

Whenever I opened the drivers door on my 1967 Cadillac Eldorado the interior lights would not come on. Only the red warning light in the door lit up. Everything worked from the passenger´s side though. So I had to check out the door jamb switch. I unscrewed it and checked the three cables going into it. One cable is for the warning light in the door, one for the front interior lights below the dash and one for the rear interior lights in the C-pillar. I made sure that all contacts were in place and had to bend them a little. After a little tweaking the lights started to work again. When I screwed the switch back into place, the rear lights went out again. So I had to adjust the contacts once again and now everything works perfectly. Great to have the interior lights come on again when I step into the car.

This is how the doorjamb switch looks like on a 1967 Eldorado when removed. Sorry for the crappy cell phone picture!
I will have to clean the paint in the doorjambs soon as you can see in this picture...

The 1967 Eldorado headlight door repairs - first spring outing

As we had an unusual warm day today with the snow melting in front of the garage, and having a couple of hours of spare time at hand, I decided to drive the Eldorados out of the garage. They both started right up as soon as the fuel pump delivered fuel to the fuel bowl. Both cars idled beautifully and it was a pleasure to see them in the bright daylight again for the first time since last October when I had put them into storage.

While I had the 67 Eldorado out I also turned on the headlights and was once again annoyed by the fact that the right one opened simultaneously, but closed slightly slower than the left one when I turned the lights off. There was a difference of around 1 second in movement between the two headlight doors.
Being a perfectionist I could not stand this, so I began searching for the problem. I already had spent some time in the past trying to fix this, but I did not succeed. The system is driven by vacuum only, so I started to look through the vacuum hoses once again. I had already exchanged a couple of them last year. I found another two brittle ones going through the firewall to the headlight switch from where a slight hissing sound was coming when the lights were on. When I touched them the hissing would become even more noticeable. I then tried to press them onto the connector of the switch and the first hose began to crumble into pieces. So I replaced all the hoses on the switch and rerouted them through firewall through the rubber insulation. There are three hoses . One is the vacuum feed (the one in the middle - I think it was yellow), one is for opening the doors (green) and one for closing (red). I also replaced the red hose behind the firewall going to a T-connector from where the vacuum is fed to the headlight door actuators. I had already replaced the two hoses after the T-connector in the past. With all new hoses in place the doors now perform almost simultaneously and quite fast. So when you run into troubles with your headlight doors, check and replace all the according vacuum hoses first. Its amazing how brittle the hoses going to the headlight switch inside the car can become over the years. It looks like they used a quite different material for these three hoses, as all other vacuum hoses are in much better shape and do not show any sign of deterioration at all.
You can see a video of the headlight doors in action below. On this video they are slightly out of sync. As it looks like they are slightly different every day, depending on temperature and engine idle...

Cleaning the 1967 Eldorado´s Engine Bay

I spent quite some time during the last weeks in the engine bay of the 67 Eldorado. I tried to clean everything in there as good as possible. After cleaning and degreasing everything I also gave all the metal parts a fresh coat of wax. I also cleaned all the rubber parts and cables and applied some vinyl and rubber conditioner. Everything is sparkling clean now. I´m now thinking about painting some of the parts where the paint has some imperfections or is worn off. I will have to find the right correct paint first. The engine looks quite presentable now. What will get a new paintjob first will be the airfilter housing, which looks pretty worn. It will be stripped to bare metal before painting of course.

The 67 Eldorado´s Automatic Climate Control System is back in working order

Today I managed to solve the issue with the partly non working Automatic Climate Control of my 1967 Eldorado. As described in the entries below, the blower would only come on in full heat modes when the car was accelerating. The AC of the Eldorado is very similar to the one from the DeVille btw.
I suspected a vacuum leak somewhere in the system. Troubleshooting began with going through all the vacuum hoses. I replaced some which were a little worn out at the connectors. I also cut off the ends of most hoses, as they were all becoming a little loose during the last 40 years. I then plugged them in again.
Not much did change though.
When I came to the hose of the hot water valve and the delay relay, I had the first success. At least the blower motor would stay on in all “Auto” modes, even when the car was idling - but would still go off in “Fog” and “Ice”. I then suspected a leak in the power servo or in the dash controller. So I installed the power servo from my 67 DeVille where everything works perfectly, to be able to rule out any problems. Nothing changed though - the blower would still come on and off depending on the throttle position.

I then soon found the culprit of the whole issue - it was the master vacuum switch - which seems to have a problem with the internal electric switch. As I had a spare one around I installed it - and voilá - everything worked as it should. It always looked good when I checked it before.
I´m very happy that everything is back in working order. The only thing which I still have to repair is the fast idle diaphragm which completely dried out and is no longer functioning. Fortunately I do have a spare 429 engine in the garage from where I can grab and use this part - so I will repair it soon.
I then need a new condenser which is already on the way across the Atlantic coming from Old Auto Air.
By the way - Cadillactim has an excellent trouble shooting guide for the ACC on his website.

The evaporator had to be replaced as well along with the heater core. This is a pretty big task as you can see on the pictures below. You even have to remove the hood to get access to the whole unit. The fiberglass AC enclosure had to be repaired at my car as well as the previous owner tried to repair the evaporator and missed a screw and made a tear into the enclosure. The restoration shop repaired this professionally and it looks like new now.

The best troubleshooting guide for 1967 and 1968 Cadillac´s Automatic Climate Control Systems I got today from Gary Sisk - owner of a 1968 Cadillac.
This is a very easy to follow explanation which will save you a lot of time and you do not even need any special tools.
It was written by Lynn Nicholls and can be found on Stampies Cadillac page - here is the direct link to it.

Below you can find some pictures of my system:

The 67 Eldorado´s vacuum hoses - Blower issue

The 1967 Eldorado is now back home from the restoration shop. They wanted to recharge the AC on the day before I wanted to pick it up only to find out that the condenser is also leaking badly. I´ve ordered a new on from Cold Air Products in USA in the meantime which I will install later. The recharge will then take place in spring.

During the rebuild of the whole AC system I found out that I´m also having a little issue with the blower which does not always come on at full heat. So as a first step I started to go through the numerous vacuum hoses in the car yesterday. I soon found some old and brittle ones which fell apart when I just touched them. The two hoses that fell apart were the ones going to the right headlight doors.
Original color coded hoses seem no longer available anywhere. Thats why I had to buy regular black ones and paint the red and green stripes on them. Looks almost perfect - I did not think that it would turn out this nice.
Will go through the rest of the hoses soon. With the replaced hoses the headlight doors now work 100% simultaneously, whereas before one was slower.
I still have to find the issue with the blower motor - but I now suspect either the AC controller or the power servo. It works perfectly in full cold - only when I set a higher temperature the blower will cut out. Another problem to solve over the winter... I had almost the same problem with the 67 DeVille before which I could successfully repair.
BTW - if you know of any source for the GM OEM style color coded vacuum hoses please let me know.
You can find a vacuum diagram for the headlight doors here!

edge
There are lots and lots of vacuum hoses in the Eldorado to check - here are only a few going to the storage tanks...
I will also give them a good cleaning during the winter.

The new hose with the painted red stripe is already in place - looks some kind of original...

The 67 Eldorado passed the inspection

Just got the news from the restoration shop that the 67 Eldorado passed the state inspection and has now all the necessary paperwork to be driven on Austrian roads! YEEEHA!!!! It is now "typisiert". (thats the german word for this inspection procedure which privately imported cars have to go through to get a license for Austrian roads)
The completely rebuilt AC will get a recharge next week and I can then pick up the car and put it into winter storage together with the other Cadillacs. Can´t wait for the next cruising season.

The 67 Eldorado is now at the shop to get an Austrian license

All cars imported into Austria have to pass a technical inspection to get a license. Its an inspection done by state inspectors where they are checking every car thoroughly.
The cars have to be safe and in very good condition. They check the brakes, all the suspension parts, rust, emissions and everything else what is important. The regulations are very strict - so basically everything has to be in perfect order. We even have to change the lighting system. Its obligatory to have amber rear turning signals, which makes it impossible to keep the rear lighting system in original condition (at least for the time of the inspection...). Often there is no other way than to install additional amber turn signals somewhere on the rear bumper or trunklid. (!)

The 1967 Eldorado is now at the restoration shop - here it is on the side of a nice low mileage 1971 Lincoln Mark III.


As I finally want to be able to drive the Eldorado on our roads, today I delivered the Eldorado to my restoration shop, where they will do some of the necessary conversions and repairs. They already helped me with my 67 Deville and the 58 Eldorado.
The Eldorado will now get a new radiator as the original one is leaking badly. Actually I will have the original one recored and repaired. The front disc brake will get an overhaul due to a partly sticking piston, together with all new brake hoses. The fuel line will be replaced as it started to leak as well. The lower ball joints and the idler arm will get exchanged along with some rubber bushings. Besides of this list of repairs the rear lights will be converted for the inspection.
After the Eldorado is back in perfectly working condition, the inspector will check the car and hopefully approve it... Unfortunately until all this will be done it will take some time, and the winter is just around the corner - so it will go right back in winter storage after this procedure.

As our 96 RMW did not pass the technical inspection 3 weeks ago I had to order new rear wheel cylinders which were installed today as well. It then passed the annual inspection and can be driven for another year.

1967 Eldorado - the headlights and the ALC work again

Yesterday I finally found the time to spend a couple of hours in the garage and deal with the problem of the non working headlights and the defective ALC of my 67 Eldorado. I got some great tips from Glen (see a couple of entries below). With his great expertise I could solve all the problems. I installed a set of new original style spring clamp battery cables from Antique Auto Battery and repaired the blown fusible link for the headlights. The new battery cable comes pretty close to the original cables that came with the car. I would say they are 98% correct.
I also got a new control valve for the ALC compressor from Arizona Vintage Parts (a company I highly recommend). With this new valve the ALC is back in working order and the car is now raising its rear to the correct riding height again.

The first 1967 Eldorado parts arrived

Last week the first parts I will need to get my 1967 roadworthy arrived. Some more are on their way to me from the USA. I ordered them from Rockauto, Antique Auto Battery, Coopers and Arizona Vintage Parts. When everything finally arrives I will start working on the Eldorado again.


The first few parts that arrived - belts, filters, gaskets, caliper repair kits, dryer, pitman arm, air filter and some other stuff....

1967 ELDORADO HEADLIGHT ISSUE - ONE STEP FURTHER

As my headlight suddenly stopped working recently, (see two posts below) I spent the afternoon in the garage for troubleshooting. I got a very good troubleshooting guide from a fellow Cadillac enthusiast from the USA.
Glen wrote the following:
“If you take the panel under the steering column off I think you can reach up and disconnect the connector from the light switch. Or you maybe able to get a meter probe up there to check voltage. The battery connection to the switch for the headlights is on the 14 gauge yellow wire. This only supplies the headlights and front parking lights. If you have 12 volts there then your problem is in the switch. There is a circuit breaker in the switch and it may be bad or the contacts in the switch are bad. IIRC these switches have a vacuum switch on the side that operates the headlight doors. This makes them hard to find. They do not interchange with the 68 Eldorado because in 67 the parking lights only come on when the switch is pulled out to the first position while in 68 the parking lights come on with the headlights also. If you do not have voltage on the yellow wire then you should check the fusible link on the starter. It is an 18 gauge dark green wire that changes to a 14 gauge red with white tracer before it gets to the connector. Check for 12 volts at the connector and check the contacts in the connector. “

Glen was spot on with his diagnose and it turned out that the green 18 gauge fusible link was the culprit for my headlight problem as it came apart for unknown reasons.

the green wire once was a fusible link - it fell into pieces when I slightly pulled on it


As a follow-up Glen recommended the following:

“You might want to look closely at the break in the link. See if it is melted or did was it broken by mechanical means. If it was just pulled apart or cut then you have to check what caused that. To trouble shoot this if it was actually melted due to over current, I would unplug the headlights and front parking lights, and temporarily connect a headlight or other big light bulb, in place of the fusible link. You can then try things without blowing fuses. With the troubleshooting light in place it will light up brightly if there is a direct short. With the headlights and front parking lights disconnected the test light should not light up at all under any condition. You should be able to move change the position of the headlight switch, switch from high to low beam (light switch in the headlight position); wiggle the wire harness anywhere and not light up the test light. If it does you have found the short.”

I did this procedure today but it did not show any shorts. I then reconnected the front lights and everything did work again. I will now have to find a replacement fusible link which is very uncommon over here in Europe. I will replace it together with the positive battery cable where the clamp is almost falling apart. I hope the issue wont come back. It looks like the fusible link maybe only fell apart due to age as it did not show any signs of burning. Its located very close to the starter and the exhaust manifold - so maybe 42 years of dirt and heat just made it crumble into pieces....

New pictures of my 1967 Eldorado on my website

When I drove the 67 Eldorado home from the shop last tuesday (see report below)- I stopped at the park deck of the local shopping mall to shoot a couple of quick pictures.

1967 Eldorado Inspection - ALC issues and dead headlights

I took my 67 Eldorado to my restoration shop yesterday to have it checked for the Austrian registration.
When I arrived there the headlights did no longer work. They did not have any problem before.
When the inspector wanted to turn them on - the headlight doors did open but the lights did not come on.
Also the parking lights and high beams do no longer work. The taillights did come on though and the cornering lights and turn signal do work as well.
Very strange… Checking the fuse panel I found out that there is no fuse for the headlights. My guess is now that it must be the headlight switch - can this be repaired? The shop manual mentions a 25amp circuit breaker in the switch but it does not mention how to repair it or check it.

The other thing which stopped working yesterday was the Automatic Level Control. The vacuum operated compressor in the engine bay seems to work as I can hear a ticking noise, but the car does not raise. I also added some pressure (100psi) to the service valve at the compressor but the rear of the car did not raise at all. When I depressurized the compressor the car did not come down any further either. Very strange… I really need to get this fixed - non working parts are making me crazy!
The car lost the yellow plastic cap which is located on the top of the regulator valve while driving it into the shop. Unfortunately it landed directly below one of the tires and was crushed to tiny little pieces. I will have to try to find a replacement. I have no idea how this could have come loose.

The car did not pass the inspection for some other reasons as well , like a sticky front disc brake, worn ball joints and pitman arm and some other minor things . It will keep me busy repairing all this for a while. Whats worrying me most is the headlights and the ALC as I do not have any clue at all.
On the positive side - the car was a pleasure to drive the 60 miles to the shop - its so much different to the “regular” Cadillacs - Big, silent and powerful and no big boat ride ;-)

1967 Eldorado detailing

My buddy Tayfun came to visit me for three days to help me with detailing my 1967 Eldorado and to exchange the brake booster and master cylinder of my 67 DeVille.
The Eldorado got a wet cleaning treatment of the carpet and trunk and a full detailing of the interior - which looks like from a new car now. We also started to clean and polish the original paint but ran out of time. We only finished the hood - but the before and after difference is amazing. More work will be done soon.

washing and brushing the original rubber floormats...

...they turned out as if they just left the factory - awesome - this Meguiars rubber treatment is more than fantastic!

Tayfun - wet cleaning the carpet and trunk - looks like new now as well - the low miles are showing on the interior pretty well

The hood´s paint came out really fine and smooth - unfortunately we ran out of time and could not finish the rest of the paint

1967 Cadillac Eldorado radio replacement attempt

My 1967 Eldorado originally came with an AM radio only, which is basically useless in todays world. The seller of the car put an FM/AM unit in the trunk which he had for the car but never installed it.
Today my wife helped me trying to replace it. It is always a pain to get the old radios out, as the electrical connectors are pretty hard to reach if you have big hands like me... After some fiddling and lots of bad cursing, the radio eventually came out. During this procedure I found out that somebody messed around with the speaker cables which go to the rear speakers and installed new ones - which were connected directly to the front speaker. They cut the wire going to the front speakers and spliced in the rear speakers. Not very well done...

When I finally managed to install the “new” AM/FM radio I found out that it does not fit at all... It either comes from a 66 or a 69 Cadillac?

So I installed the old AM radio coming from my convertible where I did the same procedure 2 years ago - only to find out that non of the 2 speakers seem to work anyways...
I now have to find a good used 1967 AM/FM radio and 2 speakers - the list of things I need is getting longer everyday. I will also have to repair the wiring of the rear speaker back to original.
Thanks to my wife Afra for helping me!

Cleaning the engine bay

Today I started cleaning the engine bay of the 1967 Eldorado with its mighty 429cui V8. Amazing how much dirt could collect on a car with only 27k miles on the clock. Its a pretty dirty job and will keep me busy for a while. Surprisingly, below the thick, oily and dirty surface there is still some shiny paint appearing!
I hope though, that I will ever be able to get my hands clean again as well... I guess I should wear a pair of gloves next time...

This is how the engine bay of my 1967 Eldorado looked before cleaning - I will also have to install the new evaporator later, reinstall the blower motor, connect all the AC hoses and recharge the AC... lots of work ahead
.
The engine degreaser is pretty aggressive on the oily gunk and dirt.

The first pictures of all 3 Cadillacs side by side

Today I took the first picture of all 3 Cadillac side by side in front of the garage. Unfortunately it was shot a little too late as the sun already set. Will try another time again.

The 67 Eldorado arrived!

Today was a big day, as the 1967 Cadillac Eldorado I bought in March finally was delivered to my door after its long journey from North Carolina. It crossed the Atlantic Ocean on a ship coming from Charleston, SC and landed in Rotterdam where it was unloaded from the container. It was then transported 1000 km to my home in Austria on a truck.
The truck arrived at 3 pm with the 67 Eldo and the 69 DeVille which I bought for a dealer here in Austria. Both cars had empty fuel tanks and dead batteries so we could not start them and had to push and pull them from the truck, what took as quite a while. This was very exhausting work, but eventually we had the cars parked in front of the garage. I poured some gas into the tanks and installed batteries from my other Cadillacs. I then turned the keys and the cars roared back to life without any problem. The 67 is a very nice survivor with only 27k miles on the odometer. It drives like a dream - I´m very impressed. The biggest surprise for me was that it has disc brakes on the front - I always thought it would come with the basic drums and not with this very rare option.
The cars got a quick wash and were then parked inside the garage.
Tired and exhausted, but very happy I finally went to bed thinking about all the work I will do in the upcoming weeks. Stayed tuned!
If you are interested about the cars history and how I found it visit my history page!

Here are some pictures of when the car arrived:

yes - they all fit in...

nice sight in front of the original 1967 Cadillac banner

its narrow - but they do fit in

looking into the garage - nice view...

the mauve 69 was picked up by its new owner - a dealer in Austria - it will be for sale there soon. Its a really nice car which I would like to keep if my funds would allow it. Whoever will buy this car, will get a nice Cadillac in a stunning color combination!

The 67 Eldorado arrived in Rotterdam

Last week the new Cadillac arrived in Rotterdam. In the meantime it was unloaded out of its container and the custom declaration was done. The car is now waiting in a warehouse to get picked up by the car hauler and get trucked to my home. This will be done by the end of this week. The car will then be delivered to my home in the first week of June. Cant wait to finally see it in real life. As soon as it has arrived I am going to snap a couple of pictures and upload my brand new website which will feature this new car in great detail.
