I would like to convert my AC to the new R134a because my compressor took a dive so I figure now would be a good time since I am rebuilding my engine. What do I need to replace besides the compressor. I was told to replace the compressor, drier, o-rings, and the little filter that is inside the lines. My AC line are about a year old. Anything else or special I need. :bb

 

The fittings for R-134 are also different
