Easy A/C compressor replacement

Search for "Sanden" here. There are several after-market bracket kits for it, maybe $150. You will need to change or adapt the hoses. You won't need the metal suction bottle.

Re refrigerant, best approach is to keep using Freon. Before changing to R-134A, (difficult and works poorly), read up on HC mixtures that work even better than Freon. Many people scream they are unsafe, but most haven't used them nor intelligently read the available info. According to the EPA, the only "legal" way to use HC is to first convert to R-134A (flush & change all oil), then convert to HC (which was happy with the original mineral oil). Thus, no shop will touch it. But you can do at home, just put R-134A type charge ports on your new hoses. GhostBusters was right that the EPA is out of control.
