Can anyone send me in the right direction. I am looking for a correct air cleaner vent tube for my 1968 Firebird 400. I purchased one from Ames Performance but it came to me and it had spots of rust on it. I returned it and asked for another one. But they said all their stock has rust spots on them, and at this point they have no idea when more stock will arrive. Can anyone point me in the correct direction to find one?
