1963 Galaxie Selectaire pag

[Roadpig]

I can’t find anything that will tell me how much pag oil to put in my 63 Galaxie. I had it converted to 134A 2 years ago along with a new Sanden 508. Need to replace compressor due to noise- going to remove receiver drier and have it rebuilt-Will also clean out the condenser. System holds 2.25 of r12 so I figure will need at least 1.8 lbs of 134a (28oz). Sanden website says a 24oz to 40oz 134asystem should use 135ccs of pag oil (4.5 oz). Does that sound right for the entire system? New compressor comes with 7oz installed

Thanks
