I have what may be a surprise for you.......you could do noting more than just charge the existing R12 system with R134 and it'll work fine. To discourage leakage on the compressor shaft seal, remove at least a few ounces of the mineral oil, or for that matter as much as you can drain, and replace with the exact same amount, then charge with 134. If you really wanna get fancy you could swap orifice tubes. Just be aware that the volume requirements of R12 and R134 will not be identical but if you're charging by pressure then this will largely be a moot matter.
