For R-12 retrofits, get one of the Johnson's Freeze 12 kits on ebay. Kit has sealer, oil, and three cans of Freeze 12. Freeze 12 is 75% R-134a and 25% R-502, cools like R-12. The kit also come with the sicker for letting everyone know your system has Freeze 12 and the special fitting adapters you are "suppose" to use on a Freeze 12 system.. If ever needed you can always top it off with 134a. I have also "heard" that a can of Freeze 12 in a 134a system that is not cooling will will really make it cool.
