I know i will get yelled at for this but, here's what I did to "re-charge" my system with 134a. I depressed the little air valve on the low side until the hissing stopped and then i pumped in 134a until the gauge said it was full. I just bought an at-home DIY kit at NAPA and did it in my driveway. It worked pretty dang good until my compressor stopped working. I just had that replaced and the guys at the shop recharged it for me and now it blows colder than ever. Moral of the story, it might be cheaper/easier to have someone else do it. Or better yet, ask an AC shop what is required to do a conversion. Good luck! Kudos to you for wanting to do it yourself!

I know there is a cheap way out and they make a refrigerent that works in R12 systems and is like a replacement for R12. But, you have to know someone with a MACS certification to get it.

I was at Autozone the other day, and they had a retro-fit kit for r-12 to r-134 systems. It contained a small can of oil that will mix with any old r-12 oil. I didnt fully read the package, but it might be something to look into.

Ya, that's probably what I used. some retro-fit thingy plus a can or two extra of refrigerant. but mine worked for a good couple years before it started killing my compressor if azaviator is correct about that (i have no idea). but when my compressor went it was a load on the engine and you could feel it...
