"I will throw in that the Melling pump has very nearly the same diameter shaft, within a few thou., and the same bearing length (2 inches) as the Packard, also no bottom bearing."

I'm not sure what Melling pump u r talking about. THe HEAVY DUTY Olds pump by MEllING et-al DEFINATELY HAS A LOWER BEARING. THe standard Olds pump by Melling and others does NOT have a lower bearing. It is the LOWER bearing that distinguisehes the HEAVY duty from the standard pump Olds pump regardless of manufacturer of the pump.
