I am Converting a 1975 auto SB to BB (ZZ502) and need an alum. radiator, electric fans, headers/exhaust (side pipes), pulley system (I would prefer serpentine):

This is a great radiator/dual fan combo for you. It is a large 27.5" dual 1" aluminum tubes. Our part #Sp034 for auto or SP035 for manual.
