I hope you are kidding about using propane mix. Sorry, not a safe alternative. That stuff is explosive. Use a real refrigerant. I hope you tell someone else that is working on your AC that it has that so as not to ruin an AC machine. R134A conversions work great if you do it correctly. Flush entire system with flushing agent, lacquer thinner, or a good brake clean that doesnt leave residue. Blow out the condensor and evaporator with compressed air. You will know when it is clean when nothing comes out. Back flushing helps. Replace all o rings, and put correct amount of ester oil in all the components. Drain all oil out of the compressor, as much as possible, replace drier and expansion valve, and pull a LONG vacuum, at least an hour. Fill with 2lbs (32 ounces) R134a. Good to go. I did this on my 92, and is just as cold as R12.
