I think you are doing good. Your pressures are good. As far as the fluctuation most conversions use axial/rotary compressors they come in 5 cyl. and 7 cyl. naturally the 7 cylinders have smoother pressure build up.Some gauges are dampened to make the needle steady some are not. If it wasn't cooling it would be something to be concerned with. You haven't mentioned refrigerant oil, but as deep as you go in to A/C repair, I'm sure sure you know about that. I think you're good to go. Can you tell us what you think was the cause and cure. Nice work.
