factory air and 134 a refregerant

I do not have a Challenger yet. I was just wondering what needs to be done to a factory air car to use 134 refrigerant? Thanks Randy

The cheap and easy way is to just change put on the suction line and pressure line adaptor. Add pag oil and refrigerant. This is assuming that there is no freon left in the system. The old mopar lines are known to leak an average of roughly 20% of the freon a year, so if you don't want to contend with that issue then you could do the whole retrofit kit with compressor and lines.

About 6 years ago I went with the Classic Auto Air compressor upgrade kit

I have 3 Factory A/C systems. One uses R12 because I bought (2) 30 LB tanks when AutoZone stopped carrying R12. Two use 134A, with everything STOCK including the drier, compressor, condenser and expansion valves.
I just have an adapter hose that lets me use my old guages with a 134 tap, so everything still looks stock at the compressor.

All 3 blow very cold just like they should. The only difference is that the systems take a lot less freon before they are full.
