So what's everyone doing to deal with the R12 systems on our cars? The retrofit kits are a bit of a mixed bag, as you need to flush everything out and it's a fine line with the correct PAG oil that works for the compressor and R134a. The full on conversion kit is just that, you end up with a bit of a Frankenstein kit it terms of an 8 rib compressor with a bunch of scabbed on brackets to align and non factory hoses. Everyone says it works great, but it looks nothing like factory.
You can't buy the R12 any longer (legally anyway), even Ebay has visible made sellers make buyers at least promise they are licensed or selling it to someone who is.........lol!
Since the Kenne Bell was pulled of the black car, it needs a charge, and I've no desire to jump through hoops on the silly conversion and don't want to risk burning up my factory compressor.
