The east coast guys say unsilenced air cleaner, the west coast guys say same dual snorkle as 727.

Question for the east coast folks, of the cars sold new on the east coast, where were they built? Lynch Road?

The west coast cars are mostly LA built cars, with some St. louis built, and all ragtops are St Louis. I've seen no Lynch Road 67 B-bodies out here that were sold here new. The Certicards will tell you this info, another benefit of 67's.

Maybe this is the reason for the difference in these air cleaners, even though the only difference the parts book shows is for C.A.P.
