Can't speak for '67 Camaros, but I do own a '70 Firebird that was built in Norwood and sold new in CA (I bought it in CA, and it has the CA-only emissions stuff).
It is a bit of an oddball, though, as in all my years of messing with these cars, it is the only one I (or any of my friends) have seen that was sold new in CA and NOT built at the Van Nuys plant.
