I am restoring a '74 T/A and have searched E-Bay almost exclusively for parts. There is one guy (can't recall username right now) who sells nothing but rusted junk (screws, etc.) from T/A's that must have been pulled from the bottom of a muddy river. Every single piece is rusted or coated with dirt. You'd think he would take the time to clean the parts or throw 'em on a wire wheel. Nope. Nonetheless, 99% of his auctions end in no bids.
