I found this on CRG....Joe

The last digit is the configuration code of the pump. The 67 pumps are coded A and C. (67 Corvette pumps are coded P and are unique to that application.) The 68 pumps with a pressure relief valve installed in the pump were coded Y. Non-pressure relief valve 68 pumps were coded Z. 69 and later pumps (without a pressure relief valve) were coded S.
