We are reconstructing the front split seat, with armrest, for our 64 convertible. We are starting with the metal frame/springs. Anyone have photos/details on the foam /cushion material to get a good shape etc as the base for the new upholstery? Also reconstructing the rear seats as well so any info for them would be helpful as well.

We have the actual finish upholstery being made now.

Having the switches on the side of the seat instead of the door will shorten the distance current will have to travel. It will therefore reduce the risk of shortage. I have the 6-way seat in my Series 62. Have no issues or problems putting down my left hand and adjust. On my -66 DeVille Conv. the controls was also on the side of the seat. I Believe they did have a reason to move away from cables constantly being "bended" when open and closing doors. 

Its a lot of current to operate the front seat. Rerouting via the door is not recommended.

Power for the seat motor is fed through the large red power feed wire from under the dash direct to the motor for both style seat switches. You have a low current "switch" circuit from the seat switch that activates the relay to close the "power" circuit feed to the seat motor, or activate the appropriate transmission solenoids. Just wanted to point that out.  I will also note that I have also seen several examples where the wiring harness for the Series 62 seat, which is confined over the seat rail on LH side of seat, work lose and get caught up in the LH seat rails and break and short, so it is not like there is no risk for failure on a Series 62.
Personally, I would leave the seat setup the way it is, but you indicated you already have the door panel with the seat in the door panel, so I'm just saying you will need the other harness if you do go that route. Also, if you need the Series 62 harness I have those in nice condition for $35.  You will probably also want a lower LH trim without the hole for the seat switch if you go this route... which I have... and I assume you have the correct switch for the driver arm rest switch plate. 


Will see if we can get the existing seat out of the car and look for the wiring . If I do not find it I will take you up on the harness you spoke of.

The car we have was made with the six way seat option -- so I suspect I may find the wire loom in the door and running as you guys pointed out in the rigid body feed conduit under the sill plate.

To clarify I am working on a 64 deville convert that was originally  made with the 6 way seat option, it currently has the six way seat option working with the controls on the drivers side of the seat. The door panel and its controls are also to be replaced with the correct '64 controls and trim pieces.

I have purchased a correct seat , with the center armrest and the lower left trim without the hole for the seat switch-- to replace the incorrect seat that someone put in the car probably back when they made it look like the '63 that was in Scarface.

Thanking everyone who is responing  to my request for information- all very helpful

Anders ,

Thanks for the info, can already see that opening and closing the door can damage some wires.


There is a post on this site by Maurice Lapoiinte, It was titled "My interior restorations, pitfalls and things I have learned.  His was a 63 Convertible but he posted a lot of pictures and would think that there would not be much difference between 63 and 64 seat upholstery bases.  I could search his page site and find it hopefully you can too.  Trying to search just by title did not get me anything so unless Jason can help you some other way just try to get to his site page,  It will definitely be worth your time I think.  Hope this helps.

Gene, Thanks for the info about Maurice Lapointe. Located his post and it is very helpful.


Hello tom.

Maurice lapointe here. I have completed my front and rear seats on my 63 convertible now ,but not yet installed them. I have taken pictures along the way and was going to add to my post for everyone to access,but haven't got to that yet either.hopefully soon.You can contact me at moefurd@telus.net and I can send pictures to you direct. As I said the interior is still out if you want a picture of the wiring harness routing also.drop me a line.


I decided to finish off my posting of the seat rebuild I did.hope this helps out others.


So HELLO, Back working on our 64 convertible. Want to screw on the outer lower front seat base metal covers on the six way front seat. the rear end has a hole for one screw and i see what it connects to. The front end has two screw holes about the same size. Question is what do those front screw go into?? what the parts name and who has the part--one for each end of the seat???? thx

On the 6 way bench seat, the one rear screw, screws into a bracket that is mounted on the underside of the rear of the seat rail. The two front screws go directly into holes on the base of the seat frame ... there is no bracket. Look closely and you should see some holes, unless they have been covered up.

Jason, Hi , Nice hearing from you. I can see where the single rear screw goes. The front two are the ones I am not seeing incorrectly then. There are two holes on a metal part BUT it looks like it is an inch or so space between the bracket holes and the  side cover holes . Will look at it again tomorrow and see what i saw wrong?? Passenger side looked like it had remnants of a plastic part riveted to it.

Will get back to you tomorrow. thx again

Here is a crude picture... should be right down there at the base: 

and for reference here is that bracket where that one screw goes:

Lower Front End Ball Joints

Posted by Logan Robb on May 11, 2023 at 9:04am 7 Comments

Good Morning all! 

I took the 64 into the shop to have some adjustments completed and in the process decided to have the lower ball joints replaced as was recommended the last time I had it in. I ordered the parts and came into the shop. They quoted me nearly $500 to replace those lower ball joints requiring nearly 4hrs of labor. Now this is a reputable shop and they know me by name here and they will continue to get my business. I am just questioning what on earth is…


1964 power steering sector rebuild

Posted by CHRIS CARLSON on March 20, 2023 at 11:32pm 3 Comments

 I'm having my steering sector rebuilt, and considering changing it from 20-1 ratio 4.2 turns lock to lock to 3.5 turns lock to lock @ 16-1 ratio, If i change from a 3 1/4" box to a 3" box i could have a 14-1 Ratio steering response would be faster, shorter distance to turn the wheel to get a response,   has anyone done this? and how do you like it? thank you
