Tracy, the only dimension I am not sure about is the counter bore
on the front side (psru side) of the plate that locates
the thrust bearing race. The PSRU plate that you sent me does not
have that modification. What are those dimensions?
I scaled your drawing and I got 2.04 OD and .031 deep.

Blake, here are the latest hole dimensions and my version of Tracy's drawings. 
The zip file is both IGES and DXF.
