Help identify a part for a Corporate 14 Bold Rearend - 1980's K30 4x4
When I removed the rear axles there was what looks like either a shim, gasket or compression washer between the flange and the axle housing. I left this shim with the truck but have a picture of the axles. I'll get a picture of the exact part but here's a picture of the axles to start with.

Thanks guys ahead of time...
Heading over to the truck right now to continue re-assembling the rearend and frontend.
