A friend of mine lives near a couple of "Pull A Part" junkyards. Both are huge, fully paved and keep older stuff until it's stripped clean. They also have "menu pricing", so a grille for a '71 Cuda is the same price as one for a diesel Chevette. Obviously, that kind of thing doesn't happen much, but he has picked up some really nice parts for his cars (ranging from classic muscle into the J-body era) at bargain-basement prices.
