What all years of Chevrolet 6 cylinder air cleaners are the exact same as what came out on a '66 w/250 6 cylinder? Were they oil bath cleaners in '66? It's the only thing missing on my new to me '66 C10 that I just posted pics. of. I've found one on e-bay for a '55-'59 but I don't know if that's exactly like the '66 or not. Very much in need of a good original one.
Thanks,
Mike
