I discussed the panels questions with my mechanic. I do have a hang-on conversion system. The A/C hoses are of later design and do not leak R134. I do have a sanden compressor.
The Plan: To save shop labor costs I will be disassembling the dash to allow more complete searching for the A/C leak with dye and the sniffer. I will have the idle head pressures and compressor function checked. I will concider changing to a Kiki compressor and a parallel flow condenser and going back to R-12 depending on where the leak is located. If the evaporator is the problem then I might try the condenser replacement and installing the US spec evaporator housing.
I appreciate all the info, advice and suggestions.
