How Much R134 for rear a/c Suburban?

Going to recharge my A/C today at my shop (work for a car dealership).
Lost some R134 over the weekend. After we evacuate it, how much should I tell my techs to put in it? How much oil? It's a 454 R20 1987 Suburban.

Has it been converted to R-134? Up til ~92 or 93 they used R-12 which is much more expensive now since it's getting rare.

5.25 pounds for r12. I believe with 134a you only use 80% of the r12 amount.
