Pic of the instructions is below, with my notes scribbled on it. Both holes measure as i wrote on the sheet, a numbered drill (mics at .082) fits a bit loose and the other (mics at .086) won't go in.

I've got a new 10-vane pump on the way, Wellington Parts number A74531AK. I believe it's got steel rings, but the description on Amazon doesn't say. Any way to confirm?

I'm also going with hole A = 3rd and C= 2nd?

Regarding the .500 boost valve, the trans came with a .420 in it. For a stock converter, stock 350 engine, 3.73 rear gear daily driver (that might see some performance add-ons in the distant future), would either boost valve be preferrable?
