Yours is a later model long pump, and my Napa pump was an early model short pump for 68-72. It had an AMC part number on it so had to be a reman, I bought it around 2001 or so.
We can't see the top of yours from the pic but the later model pump will have the bypass clocked at the 12:00 position as well as the 4-3/4" or so length.

To add to your great thread...
I purchased a standard GMB pump for mockup for working on my mixed year parts engine setup. GMB 110-1040A It seems that it shares the same shaft specs as the performance GMB pump. QUESTION: IF the diameter is the same from flange to bearing for the oem late pump version... Other than the impeller difference, I assume the GMB shaft design with its corresponding bearing, will be a better option than the factory with smaller diameter shaft at the bearing? Only if we had a bearing OD to compare with between the GMB pump and late model oem pump, to see if there is a slightly larger bearing bore OD at the GMB snout, for the larger GMB bearing ID... "If" the above question is validated by a confirmation on bearing ID size differneces between OEM and GMB. |
