well guess i'm not gonna need an alternative to R12 after all, cause the compressor is shot and there are leaks all over the system according to my indy.
it would cost too much to keep kool with no guarantees of success...
perhaps the money would be better spent on some other stuff the car needs
at least it got the trans fluid changed while it was on his lift
