If you want to look for used ones, 1974-'78 Chrysler, Dodge, and Plymouth will all be the same. Just like with the older body styles, the length difference is in the rear floor pans.

You can buy bulk material from McMaster-Carr.

The hard part is figuring out exactly what you need.
This is what I bought to make new tail light gaskets for a Toyota Camry.

It sounds like that Permatex 81730 would work fine. I doubt that it would fog the glass futher.
The official product used for decades to seal the glass to the gasket was liquid butyl. Looks like there is still one company that makes it. It comes in a pint can that you can attach a hand...
Those wheels look much nicer on a New Yorker than they do on a Cordoba.
The red centers go well with your white and burgundy car. I don't think they would look as good on a green car for example.
Jeff
I think they were 1978 and 1979 on the Cordoba's.
It's tough to find a complete set, but not unusual to find the aluminum wheels without the centers. Every so often I'll see some wheels and some centers for sale at Carlisle.

I would try paint remover/stripper. I don't think that it would attack the plastic. The modern paint strippers aren't as aggressive as they used to be.

I buy much of my general hardware from Bolt Depot.

Altha Fastener has a good selection of automotive specific hardware. They appear to be closed until November 6th, and the website is inactive right now.

You'd have to find someone parting out a fairly solid C body convertible.
I don't think anyone here is doing that right now.
At least it's an area that doesn't show, so the "function over form" method can be used to speed up fabrication time a bit.
Jeff
The answer to the original question is Yes.
You can swap the big block sub frame into your '79, and all will be fine.
As mentioned, the trans, exhaust, radiator, engine wire harness, etc will likely need to be swapped too.

I won't be of any help on this subject.
I haven't done any vinyl tops yet. I do plan to tackle one in the hopefully not too distant future when it's time to get one of my '73 Gran Coupes ready to sell. That car will require the same top that has been causing so many headaches with the...
Here's some photos. Let me know if you need something different. I tried to pick a few different reference points. It's kind of dark where the column is, so they aren't the best.
It's about 5-3/4" from the surface of the bearing retainer to the step in the shaft.
With the tape measure...
I don't think you can easily or accidentally collapse the center shaft on a C body column because it has the lower bearing to hold things in place.
I should have a tilt/telescopic in inventory. I'll see if I can get a measurement off of it.

As John said, they were filled and smoothed from the factory.
That was a trouble prone area on the convertibles. The car tends to flex there and the factory filler will crack. My friend has a 40K mile 1970 300 that's all original paint except for the dutchman and tops of the quarters because...
Here's the booster and pedal that you need:
Looks like the car is at French Lake Auto Parts. You can look them up on the web or contact them through the ebay listing. I've bought some parts from them in the past and they were decent to deal with.
NOT MINE - 1968 Plymouth Fury I 4dr Sedan...
What vehicle are you looking to get the work done on and does it need significant metal repair?
Many shops have been spoiled by the AMD and Goodmark parts, and are no longer interested in working on anything that they can't get reproduction sheet metal for.
