[Stocker]

A little info from my notes, from when my AC was converted to R134a a few years ago. Pretty much everything was done same as yours.

Stock system takes 60 oz R12 + 10 oz mineral oil. Those amounts (or at least the refrigerant) is reduced by 20% when converting to R134a.

So the correct amount of R134a is 48 oz. I'm not sure about the amount of PAG oil that's required. But you say your new compressor already has it so you should be good to go.

I hope this helps a bit, but don't take it to the bank. Verify against other sources. Others here should chime in with more / better info.
