I would replace the accumulator, orifice tube, and the compressor(unless its new). Run a vacuum for about 45- 75 minutes. Check fro leaks. Then add 1 can of Freon and check for leaks. No leaks then go ahead and top it off... I would not mess with the R-12....unless its free. Yes will perform better, but will cost and then if you have a leak or run into any issues, it will cost you too much. I can not notice the difference in the 12 and 134a , unless i take an actual temp reading. also replace all the orings... if you have a union or it has threads, it will have an O-ring(lube them with refrigerant oil).
