A/C Capacity?
 

Could anyone give me the number, in lbs, of how much refrigerant a stock A/C system in a 77 Grand Prix would have?

Thanks!

my records say 56-60 oz. of capacity for the 77 system.

SHOULD BE 4LBS (ALMOST 4 CANS OF DURACOOL OR 4 CANS OF R12)

your weight does not match with the no. of cans. Cans are not 16oz, so four cans is less than 64 ozs. (4lbs), so which is correct?
