Last set I got came from Tri-City Plating Co. Inc. - Chrome Plating for the Tri-Cities and surrounding areas and they're nice pieces. May have to find a core to send in though if they don't have any.
Mine had a giant washer put in behind the striker (not ideal). If I was going to weld anything in there it'd be one of these Dynamic Renovation - 67-76 A-body Passenger Side Door Jamb Repair Plate
Probably the reverse of what I did. Doors, weather strip channel, a pillar trim (can be made to work though), rear plastic trim to match the upper of the doors, trim on the quarter glass was different. If you're game for hacking stuff up can probably use all the later guts in the early door shells.
This shows a green stripe but I don't recall ever seeing one, I wonder if it's a bright green like the E bodies got though. I'm sure you could get one made in a similar shade of green though.
M31 belt molding. You could get it on Dusters, Demons, Darts and Scamps. It isn't reproduced as far as I know and the corner pieces for the rear sucks to find in decent shape. I can take photos after bit if needed, I added it to mine.
Right off of PPG's site " MP170 Epoxy Primer. Primary use: bare metal adhesion and corrosion protection." "Can be applied over: Properly cleaned, sanded, bare or primed steel, galvanized and aluminum." So yes, it can be applied to bare metal.
There was no mention of them in the '70 sales book, just left and right manual and a left remote. '71 book states they come as a pair "Racing, outside left remote, right side manual, color keyed or chrome"
I'd just pay the extra for AMD, I went with the cheaper sherman or goodmark option (been too long) and they're stupid thin. I could pop them in and out by hand if I got bored enough.
Appears so according to DMT's site, probably just helps to keep water out so you don't blow bulbs. Someone smarter can answer about them being glued on though.
Sadly that's the only place I recall still having any listed. May just have a bunch of filler up top from trying to blend those quarters on, could possibly be able to use AMD ones. Inspection camera or similar would be handy to check out the back side of the quarter.
The guy that used to make the good repops recently passed away so you’ll probably not find many good copies. The one in Canada I believe is a little small (used the inside for a mold).
Dura-block has a nice set of blocks as well as some 20+ inch ones for say quarters and doors. DIY Auto School on youtube has some good videos as well as other places. Just use a cheap black spray paint for a guide coat or SEM makes a guide coat. Key is to take your time with it.
Probably better to learn yourself, it's not too bad to learn to do. Most expensive thing you'd need is a welder and good air compressor. I'd hate to know what mine would have been at a shop.
