Well guys it all depends on how much is actually damaged. It may be just one or two things that may need to be fixed or replaced. the other things just may need to be reconditioned. the entired system should be flushed , though. The drier should also be replaced or rebuilt. I can rebuild an rv2...
I specialize in rebuilding RV2 compressors, both early and late models, clutches, plunum boxes, line, hoses, condensors, filter-driers, 134A and R12 systems. Remember, original a/c adds another 10% to the value of the car.
