Holley and Kwik are your best options IMO. They both have options for spacing from Vette, f-body/gto and truck. (Just order correct spacers for your application) they mount the compressors up high and you don't need to worrie about weather or not you have the proper bolt holes in the block, as with some of the low mount stuff. You really want to make sure you are running a sanden compressor if you are using vintage air as their systems are designed to use them. Not the NEW factory GM type compressors. You can get away with running a "pancake" compressor.
