My '84 has the Sanden (barrel-shaped) compressor. The sticker (and the manual) specify 48 ounces (+/-4) of R12. Applying the 80% factor, I used 40 ounces for the R134a conversion and that has worked very well.
I hope I haven't scared off anybody by discussing how much refrigerant to use. It doesn't have to be hair-splittingly precise. The only thing I wanted to get across is that the pressure gauge doesn't correlate to quantity. Remember, refrigerant under pressure behaves very differently than "normal" gasses like the compressed air in your tires.

If you have a leaky system that you have to fill each spring, you get used to filling it without getting too precise. You would be surprised how much latitude you have with the amount of refrigerant and it will still work.
