Combines 1660 A C Capacity

I know the oil capacity for the compressor is 8 oz. The refrigerant capacity I'm not sure of. To convert, drain all of the old refrigerant oil. Should get close to 8 oz. If you get close to 8 oz., put on a new receiver dryer , which is above the cab, add the new oil, vacuum pump the system, and fill it with the R-134.

As a follow-up for everyone. The oil capcity is 8 ounces and the freon capacity is 5 lbs.
