I know my old AC system in my 69 Dart works great with the RV-2 compressor and R -134.
No. Some people hoard them but they ain't worth anything. R134a can cool just as good if you know what you're doing.
True that. The Classic Auto Air AC system I put in my Barracuda will freeze you out after a few minutes, then we have to run it on low.Yep. I can get my pick up down to mid 30's
