what about a rear spool?

The cup is plastic as is the case. This allows for flex and then the gears strip. The ring gear screws are too small. At a minimum get an aluminum diff cup, the modified ring gear with 3 mm screws and an aluminum diff case. This at least theorecticly corrects the flaws of the 3906 diff.

...or you could spool it.
