My 1990 wrangler has r12 as the refrigerant. I am not looking to be convinced to switch to R134, ha ha. I am looking for somebody who knows a shop that is 609 certified and has R12 refrigerant in stock, or what is everybody else doing to top off your R12? I called a shop in NH and they are charging $72 a pound for the R12 and tried to set me up for an appointment to put a pound and a half in but I am nowhere near there. Any help is appreciated.
