Dana 44 pinion shims

[ChevyTruckGuy68]

Hello to fellow memebers, and happy holidays. I recently started pulling the front diffderential apart on my 67 k20 to swap in 4:10 gears instead of the factory 4:56. I completed the rear swap a while ago and waited to do the front because I knew it was going to be learning experience. I have been educated on grear mesh and pinion depth (which is all very new to me) . I was wondering if anyone new good source for shims for the pinion. The shims would go on the pinion between the Shaft and the cone bearing.

Thanks very much, Andrew.
