I understand the need to fine tune the gear mesh, but how do you make adjustments? Shimming the pump?

After reading the long discussion on oil pump failures at .org, it scared me enough to make an oil squirter pointed at the mesh area. That was almost 4 yrs ago though and I don't remember every detail of the cam, pump, dizzy interface.

To me it makes sense to keep the oil pump gear running with the cam shaft that they were born with.
I used the OE 87 cam as the stick that was reground.
I used the OE 87 aluminum oil pump body but swapped in a NOS g rotor assembly, so I removed the oil pump drive gear, then re installed that drive gear on the NOS oil pump shaft.
I left the gear a bit high or out from the oil pump body, then checked the mesh with the gear check paste, then knocked the gear in a bit at a time till the mesh was where I wanted it.
I have removed the oil pump drive gear and re installed the gear on several pumps, I have a good process developed. If interested ask and I will show how I do that.
