If the smog pump part number 7802609 is in the A.I.M., then that should be the original part number when the cars were made, which is the number I'm after. The revised parts manuals show several later numbers. Can anyone who has a 1968 parts book verify that 7802609 is the part number of the smog pump as installed at the factory? If it isn't, what is the correct number? Thanks.
