You’re welcome, and thank you.Thanks for the info. Nice write up. Its amazing what one can learn on this site. This opens up a few more options and it's looking more like I'll rebuild it vs parting.
If the damage is limited to the actual diff “case” half, then you should be able to do the work with a drill press/hand drill. The precision machining for the shaft and seals is on the “lid”, hopefully that part escaped damage on yours.
