If you're looking for a junkyard with 27 to 34 coupes in it you're about 50 years too late. In the 60s LBJ's wife headed a campaign to crush every old car that was visible from the road. I think CA. still has a car crushing program going on. Any old coupes that survived would be in rural areas hidden from view behind a barn or in the woods. Rodding is very popular in the bay area so most of those have been discovered already.
Try searghing ebay for a project car or pick up a copy of Hemmings Motor News or the local classified ad magazine. If you join a club like the Bay area Roadsters some of those guys might have a project or parts car that they might sell. Rodders hate to junk anything that someone might be able to use.
Good luck in your search.
