64 4 Window rear door-door panel removal. Caveats?

While waiting for my AC transducer and power module to come back, I started to pay a little attention to the rear door window, which works but gets hung up (the back goes up higher than the front and I have to lift the front while it is coming up). I am guessing the front of the scissors is out of the track and needs to be put back-but I'm not sure and won't be till I get a look at what's happening in the door. 

Anyway, when I look at the FSM on how to remove the door panel, it advises great care in removing the "nails"that hold it on and further advises that replacements are available at the dealer. This suggests to me that removing the door panel is a fairly delicate process that is likely to break an attaching nail (if the FSM called it out when new, it didn't get any stronger with age).

So, is there a preferred way to GENTLY pull the door panel away from the door with the least possibility of breaking a "nail?"

I've seen them, but never knew what they were called. More important, I had not seen the back of a GM door panel in many years, so I had no idea what the method of attachment was. Once you mentioned the type of nail it gave me a mental picture of what I would be dealing with, and a plan of how to go about doing it. Much appreciation.

hmmm. I guess I assumed everyone knew what a ring shank nail is. I forget everyone has not been restoring a 100+ year old house for a qtr century! LOL. These are also called decking nails for the larger (10D or greater) ringed nails, but any nail that has the rings that help it grip the wood or whatever it is driven into would be considered a ring shank nail.  Some have ring shanks from the head to tip, while some (e.g. the decking nails) often have a smooth shank section below the head then the ringed section to the tip.  For the door panels you want the smaller variety of ring shank nails with rings to the head or almost to the head.

Here is a picture of a typical ring shank nail:

OK, I looked up ring shank type nails;  totally different than the Mopar spring clips I have been accustomed to. Now I get it. Thanks to all.

I have been using a flat pry bar like the one below since day one... I don't recall hardly ever breaking a nail.. just firmly pry back and work your way around the perimeter. These are simple ring shank type nails and remember using the home improvement variety small ring shank nails in the past to replace missing ones. Anyway.....here's type pry bar I use:

Thanks. I already have (and was planning to use) this tool for brake work. Not sure how I would get the WD-40 in to the nail receptacles, but I understand your point-and will try to do that.

Russ ,that sure looks like the right tool for the job! Maybe should have a Cadillac tool # .

I use this tool for a lot of things. The door panel is one of them. https://www.sears.com/craftsman-upholstery-remover/p-00904929000P?s...

Hello Norman, I've only pulled off my driver's door , but same process. I broke most of my nails &   would  probably spray a bit of lubricant like wd40 into to it first. The nails go into nylon retainers so the penetrating oil should help quite a bit . I would also get on both sides before trying to pull the nail out. take your time and be easy on em. HTH .

My power steering belt pulley sheered the woodruff key off the pump shaft and is pretty wrecked. Does anybody have a pulley for sale? Or the whole pump and pulley together?

Radiator And Shrouds

Anyone have a decent radiator and shrouds and hardware for a 1964 Cadillac deville. I have an alum. radiator and I'm deciding on to fix it or back to the original one. If I fix it I won't need parts.


64 Recirc/Fresh Air Door Actuator replaced; FROM THE INSIDE.

Posted by Norman Silverman on February 4, 2019 at 11:21pm 8 Comments

I am happy to report that I have successfully replaced the Fresh Air/Recirc door actuator that is located on the blower box-and have done so without having to remove the blower box. I did it by taking out the glove box and attacking it from the back.  It took several days, LOTS of patience and some band-aids, but it is done. THE most difficult part -BY FAR- is to remove and then replace the screw that sits on the actuator arm, connecting it to the fresh…
