Thanks for all your input. I have already removed the drier and compressor, removed the manifold hose/pipe assembly and the hose from the condensor to the drier. I also flushed the condensor and the evaporator & associated lines with laquer thinner and compressed and dried air. The compressor still turns freely and the A/C worked great until the shock absorbing material on the clutch failed.
It seems that, in addition to the $900 I have already spent for parts and freon, I can either spend another $1k for new condensor, evap (and the fun hours to replace), and all new lines, or roll the dice and put the system back together with my new drier, rebuilt compressor, and lacquer flush.
No one has commented on the life of the stock condensors - any experience?
