The differential bearing preload spacer washers vary in thickness from .254 to .290 thick. They have an OD of about 2 7/8 & ID of 2 1/2.

I need something on the order of .265 thick & another about .271 thick.

Has anyone identified a source for these spacers since setting up the pinion/ring gear backlash depends on trying something close to what's required and then adjusting their size once again after checking tooth contact patterns?

The spacer's I pulled out give too much ring gear/pinion backlash with the new bearings installed on the sure grip differential assembly.
