8 3/4 pinion shim question

So I'm rebuilding my 8 3/4 center section since there was a lot of slop in it and some in and out movement on the pinion. However, now that I have the new bearing and shim kit I ran into a bit of a head scratcher. I ground down the inside of the old inner pinion bearing so I could slip fit it and figure out the pinion depth. However, I figured if the old bearing was a different height because of wear it would be set up wrong when I press the new bearing on.

My question is this, the pinion depth seems about right with a .040" shim on the old bearing, but the new bearing is right around .010" taller than the old one. I only got .020", .025", and .040" shims in my rebuild kit. Should I run the .040" shim on the new bearing and expect it to wear in or should I run the .025" because of the taller new bearing?
