Fiberglass parts

I'm lucky in that Unlimited is (figuratively speaking) right down the street, if I want something I can pick it up and inspect it, don't pay shipping.
I'm unlucky, in that they don't make anything for the two cars I would buy glass for.
Sled city is the only place I know of that does 62 Plymouth stuff, and I haven't found anybody (in the U.S. anyway) that does Opel GT parts.
