Re: AC conversion
You might consult Marc Haibeck. When he changed my '93 over to R134a I am pretty sure the only thing he actually changed was the inlet valve for the Freon. He said that a GM bulletin that was issued at the time said you didn't have to change any equipment but did have to make sure the old system was completely evacuated. I think he did it a couple of times. --Bob

Re: AC conversion
Marc also did my 91 many years ago. Works ok but was never as cool as with R12.
