AC Compressor question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey guys...gonna be installing my ls3 soon so it will obviously have LS accessory drive with a Sanden style compressor. My 72 C10 currently has factory air that works great. Running R12 with the stock A6 compressor.

My question is, assuming I buy a Sanden unit already filled with R12 compatible oil, can I just get custom lines made and plumb the new compressor into my existing components, and continue running it as an R12 system? I figured this would be the cheapest/easiest integration into the AC system already there. Didn't want to go 134 because I'd like to keep the stock condenser, and I'm told 134 doesn't work too well unless you upgrade to a parallel flow unit.
