Default Ford 9" pinion bearing

Here's a weird one

I took my center section apart to change gears.

Some details:
Strange aluminum case (N1904)
Have an old aluminum daytona pinion support (N1927a)
It currently has a timken pinion bearing HM804846 (meant for big pinion) with a collar inside of it.
https://ibb.co/br06d0j

Has a small pinion gears on it now

I want to keep using a small pinion gear.

Is there a pinion bearing that has the same outer dimension as the HM804846(for big pinion), but has the same bore as the small 1.313?

No you have to use the bushing.

The MW part is 57602. Here is a link https://www.markwilliams.com/57602.html
There is also a flat washer that is between tithe bearing and pinion head.
Call 800-525-1963 and we will get one coming.
