I have been out on the lots of austin vee dub, and they do have about 10 or so bodies around, but most are pretty far gone...but they seem to have a good database so if you call they can usually tell you if they have what you are looking for.
the number is (512) 385-2462...and just ask to talk to used parts, I think the guy in charge is named Gary.
I also have alot of parts for 71, 73/74 cars so lemme know if that fits anything you are looking for...
