I just saw Malcolm's post back in '04 concerning pulling the impeller:
"You could pull the good impeller off your old pump if you have the three balance holes. I made up a puller and got the impeller off a '73 pump and a '68 pump quite easily. The bolts in the photo are 5/16" with the heads ground to a T shape so they can be finagled into the balance holes. I clamped the pump in a vice with the impeller up, poured water in around the seal, and heated the impeller hub. The water stops the seal frying.

Since the holes in the new impeller are smaller, I think tapping them is the only way to go. The old impeller has the larger holes so "T" bolts would work.
Malcolm, what do you mean by balance holes? Balance as in vibration or some sort of flow balance?
