I believe the conversion kits come with the R134 fittings, R134 refridgerant/lubricant, and a new receiver/dryer. The system has to be totally evacuated of the old R12. (In California, it is illegal to do this yourself!) Refilling is accomplished by monitoring pressure rather than by volume. R134 creates more pressure for the same amount of volume as R12. If you put in an equivalent amount of R134, it can burst the system and/or ruin your compressor and you have to start all over again. I'm not an expert so take this info with a grain of salt. This is the information I received when I looked into converting one of my cars to the eco-friendly air conditioning.
Frustrating to be compelled to make this conversion and just across the border in Tijuana, the R12 refridgerant sells for ~$2.50 a pint.

This spring, it's not blowing cold at all (and the compressor seems to be working). Although, when I have the a/c on, the car idles high, between 1600-2000rpm. Any ideas what might cause this? Maybe the compressor is not actually working right? I'm thinking of spending the $40-50 and converting to R134a. Aside from the kit, what all do you need? I have a might-vac vacuum pump.
