At least I can't find any evidence of them repro-ing it. It's a little different than the earlier A-body versions. The slice is in a different spot, as well as the size. Seen them on ebay for almost 20 bucks plus tax...EACH! No friggin' way. I think I can make a repro that works.
Trunk lock retainer gasket GM p/n 1718294. Fits various A-bodies, G-bodies, B-bodies, C-bodies, E-bodies, etc. 78-88. Yeah, probably some of you didn't even realize there was a gasket back there.
The GM gasket is actually made of a dense, closed-cell, neoprene foam. My prototypes are made from what I had on hand, which is some EDPM sheet rubber. My point was seeing if it could be cut and work. And yes, it can and does. I have the correct material on order now so we'll see how this goes in about a week when I get it. Design and cut plots are finalized and ready. Now I just need the right material. Plotter is set up for 65 gaskets to cut in one shot. All ready to go.
Need to find out, too, if the brake booster gasket is the same foam rubber stuff (GM p/n 9791640)...there are repros out there, but the shipping on them KILLS the deal. Try and get a $5 booster gasket and not pay 10-15 in shipping from these places selling them. Yikes. I know I can do it cheaper. May not make a slew of them, but just being able to make a cut program for it and do it when I need to is worth it. I only have 3 NOS ones of those on hand, so I may not ever really need them, but y'all redoing your G-bodies might like to have one or two. Why pay $20?
The trunk lock retainer I'm using and showing here is GM p/n 20223910. It's for a G47 Olds, 81-88, but the point is, the retainer mounts to the trunklid with a single rivet. (retainer is p/n 20014418 for 78-80 A47 but uses the same gasket)
Repro prototype made of EPDM rubber sheet. Original GM is made of thin, neoprene closed-cell foam.
