Oversize outer axle bearing 68 coil sprung 1/2 ton

[CSTGURU]

I put together a diff for my 68 as a spare, but the outer axle bearings just drop in. the housing is worn i think? even tried new bearings, same result

My question is anyone aware of an oversize bearing that works to solve this problem, or any other good reliable fixes

thanks.

P.S. first posting, here is a pic of my truck, its canadian so it has a coil diff same as all the chevys
