The differential that I am shortening is part number DR3Z-4010-A, I have the Ford Racing install kit part number M-4210-B1 however the inner pinion bearing race that is already in the housing is significantly deeper and larger in diameter than the race in the M-4210-B1 kit.
What is the part number for the correct inner pinion bearing for the DR3Z-4010-A housing?
The race currently in the housing.

The race with the B1 kit bearing.

The B1 kit race sitting inside the race in the housing. Clearly too small in diameter.
