I've spent considerable time looking -- I'm no expert but I do have experience on my side: 1) find a parts car 2) scour craigslist and e-bay (there are tools to search craigslist nationwide) 3) make it from scratch or pay someone to do the same. There are junkyards that have parts but yikes -- they will charge.... You need either a 67 or 68 Cat for most items. The only reproduction parts are those shared parts with other GM models. That's quite effective for seat frames, seat belts, etc. https://www.c2cfabrication.com/ has a few metal items but these are not perfect either. If you do find some alternatives, I hope you post as no one will be more excited than me!! As you know, I gave up on car 1 and went to car 2. Smartest decision I made.
