My car has the same number stamped on the engine and in at least two places on the frame rails. It is registered and titled in CA with this number. There is a body number on a rectangle tag nailed to the wood floor but this number does not appear on any paperwork. I've heard from others that their cars are registered and titled the same way as mine but then others who have different numbers on their paperwork such as body number or the serial number on the dash. Some say, "why would they use an engine number for the chassis number when engines can get changed" but I look at as the engine having the chassis number stamped on it.  This is how it was mandated to be done on modern cars starting in 1967.  As of then all engines were required to have a portion of the VIN stamped on the engine, typically the last 6 digits. Look at the outside of your frame rail behind the left side (drivers) front wheel just forward of the fitting where the soft brake line transitions to hard line and also further back on the same side approx. in the area below the middle of the drivers door. I think it's also on the other side rail in that same place but I have not verified just now as my car is up against the wall. I don't know of anywhere to find out what body number was assigned to what chassis (VIN) number. I doubt Chrysler saved that kind of info but who knows?

Are you sure it's from your car? I've rebuilt a lot of 1960's MOPAR front suspensions and that looks like a factory installed ball joint nut. I save them because the wide spacing of the castellations come in handy sometime.

WOW!  those are beauties. Nice score Chet.

 The three legs on the seat back fit down behind the wood strip on the floor and the seat back sits on the seat bottom.  The three legs are held tight to the wood strip with one wood screw each fastened from the trunk. (img. h shows it on the way in)

As the seat back slides down in place it comes to rest on a ledge on the upper wooden strip which I am missing in the picture. I assume the ledge had a couple hooks or a lip of some type to keep the seat back from wanting to slide forward. (img. 5) I have that little 90* angle to keep it in place for now. (img. f)

Take a look at the pictures and let me know if anything is unclear.

Both pieces are wood frame with springs.  I could make a pattern pretty easily if you can wait a bit.

The seat bottom locates by two metal "knobs" in the floor (img. 1&2) lining up with two holes in the bottom of the wooden frame. (img. a & b)  After that it just lays there.

    Okay I got some pictures. Please excuse the nasty sheets I stapled on to protect what was left of the seat covering. 

The seat back and bottom have three parts that hold them in. A pair of metal "knobs" on the floor, a wooden strip on the floor and a wooden strip with a ledge behind the seat back.

I'll try to get some pics up later today. Mine has a wood frame with metal springs and kind of just sits in there with some locating tabs for the bottom. The seat back hangs on a horizontal "ledge"which is just a piece of wood that runs below the rear window and has three vertical wooden "feet" that are part of the seat back frame structure and fit behind another wooden horizontal rail on the floor to keep it from sliding forward. After I get a few cups of coffee in me I'll go out and take some photos.

Good deal Chet. Don't you just love it when a plan comes together............even if you forgot why you made it.

I believe it is from a De Soto.

Looks like it.

I've got a  rubber backed mat covering my top to keep dry in case I have to park outside but here's some pics of the trim on my coupe. It only runs on the back side and transitions into the drip rails. The foward edge of the roof skin appears to just roll under the wood nailer that the visor mounts to, with the edge of the visor acting as trim.  If I were to make some trim from scratch I would find some suitable carpet metal that is used to separate a tile floor from the rug at doorways. If you make some pie cuts every inch or so in the metal carpet strips you can easily bend them into reasonably tight arcs to match the trim line. You may have to screw or nail the carpet edge to a piece of plywood and attach one pie cut at a time and bend as you go. When I was a kid I used to install wall to wall and we did this all the time on custom jobs. Let me know if you need any more pictures.

My 29U has aluminum trim all the way around it. It appears original and I have seen the same trim on other cars.

Looks like its just there to keep the door skin from vibrating against the wood. Here's what mine looks like.

Mine is mounted like racertb's.

Looking good Chet! I need to do that and stop messing around with pumps and regulators.
