1991 Buick Roadmaster V8 Two Wheel Drive Automatic 158000 miles

Can you tell me what the refrigerant capacity is for this car? It has been converted to 134a and I am replacing the compressor so it will be a complete refill

Do you

The original capacity when it was R12 is 50 ounces but when you retrofit to R134A, you only charge at 80% of the original charge which would be 40 ounces.
