My original system with R-12 always worked excellent but when the compressor croaked I decided to give R-134A a go. A new aluminum A6 compressor, hoses, expansion valve and drier. I used a new 11"x24" parallel flow condenser and the lower bracket from VA. I removed the evaporator and flushed it, the POA and hard lines with lacquer thinner. The POA was reset for R-134A. I had to by a 12" #8 male-female line from VA to go through the radiator support, some fittings and I made a couple of hoses. I used POE oil in the event I didn't like the R-134A results. The POA system takes well to conversion if it's done correctly. I'm real happy with it. Just yesterday I did decide to add a couple of fans to the condenser as I was going around measuring temperatures related to my fuel system problem.
