I have a 72 Suburban that I’ve been working on over the past year. It has factory front/rear air conditioning. I’m swapping over to a LS this winter and am considering upgrading to a Vintage Air unit up front to clean up the firewall and under dash a little in the process. I’d like to keep air in the rear as well for the kids if possible. Does anyone have any experience of converting an evaporator (rear unit) from R12 to R134a?? Thanks for looking and for any recommendations or suggestions.
