Hmm, does anyone know if R12 has been completely banned in the US? The last time I had the AC on my '92 here in California, R12 was still available, but it was something like $200+/pound. Fortunately, I had only a tiny leak in the system, and the machine that they used to evacuate the system actually retained the coolant, and filtered it prior to recharging the system. I only had to pay for a few ounces of additional R12 to top up the system. That was several years ago, so I wouldn't be surprised if the EPA and CARB have 100% outlawed R12. They used to sell R134a conversion kits at most auto parts stores, which consisted of the oil, the R134a, and adapter fittings, since when the auto manufacturers went to R134a, they changed the configuration of the fill/evac fittings. Just my 2ยข...
