The Archives Are Your Friend...
Use the search feature to comb the archives with topics like: R-12 to R-134a conversion, AC retrofit, AC recharge, and the like. I hope you will have a lot of time to read all of the threads you will find.
This conversion is one of the most hotly debated topics on these forums. Others include: oil change intervals, regular motor oil Vs synthetic, engine and fuel additives, antifreeze - green Vs amber, and that's just the ones that stick out...
Bottom line, some members have had success with the conversion, others have not. The basic deal is this. If your car is older and was disigned to use the R-12, the R-134a will not cool as well, could damage your older compressor that was not designed to handle the higher pressures of R134a, and it's best to stick with the R-12.
