Indeed, about 80% is usually correct. I added a new oil charge first then the 134a. Full charge on r12 was 44 oz, mine took 38 oz before the gauges read the correct system pressure and the sight glass cleared up. I probably needed a new drier but it seems ok. We'll see. I'm excited to get the rear installed and give everything a road test this weekend.
Thanks again for the donor 7.25"!
