My 72 C20 uses the Old Air Product R134A upgrade items. I think the parts are for trucks in the 73 to late 70's. I did paint the compressor black to make it look more factory. I also added a stick-on heat barrier to the engine side of the housing to help deflect heat. Not sure if it helps but it might. My AC gets down to mid 40's. It's seems to keep the small cab area very cool in the heat of the Texas summer.
