I have a '79 Bronco which came with factory equipped a/c, however I have updated to a 460 EFI from a 1990 F series truck. The a/c compressor I installed from the donor truck has the serpentine belt. I am looking for the Sanden compressor model # that has the serpentine belt clutch on it as well as the intake and discharge ports at the rear plate and pointing up. It's getting hot out and would like to get a/c going before summer's end.
