I'm about to crack open my AC system and replace a number of components. The compressor is ok right now, but... I think I may be able to get a very good deal on a Sanden 510 compressor, brand new. The problems are that it has the wrong back on it and the wrong pulley (currently serpentine). I know I can purchase a GM back reasonably, or move my old one over. Is this a terribly difficult thing to get right? Do I reuse the new seals or replace them? How about replacing the pulley? Can I swap just the pulley and keep using the new clutch? Do I need special tools, etc? Advice appreciated.
