Dear List, I need to fix my a/c. I am having a hard time finding r-12 and was wondering if anyone knows of the conversion kit to change to R-134? What should I do? If I stay with r-12 and there is a leak, I could be out some serious cash. but switching to r-134 sounds like the right thing to do. any drawbacks. Thanks Sweating in the D Joseph vin 2850 [Non-text portions of this message have been removed]
