Looks like I need to fab up my own differential bearing adjustment tool if there's none out there available. Does Miller tool still exist and sell such an item??

These adjusters don't have the "hex" shaped hole that is accessed through the axle tube. It's more like a "spanner" that would be Y-shaped with 2 dowels to lock into the adjusters and turn them.

Anyone know a source?

Any help is appreciated.
Thanks
Dean
