No you are right, Larry and I am planning to convert back to R12, but if I am, I want to replace the compressor since its been so long as R134a and since I will have to completely remove the compressor, it seems pointless at this point to not either replace it or rebuild it. LAST thing I would want is to convert, then have either a compressor failure, or have the expensive R12 leak out next year.
Its in the works for the long run, but right now I am buying a house so I can't drop $500 to do a full system replacement and back conversion
But I figure I can boost A/C performance temporarily and of even greater amount when I back convert.
I'm reading that it may not fit on the older style condenser because of the shroud used.
What about another option of fitting one larger single fan or would two twin fans as mentioned above work better?
