Tamiya Durga DB01 EP Buggy (A cheaper 501X?)

[Carno]

My rear diff screw is stripped out can't tighten or loosen it anymore. Thus my rear diff is slipping.

New diffscrews and ceramic diffbals(from ghostrc) are underway and i've already got new plates and a pulley.

The only thing i'm wondering about is if the diff plates need to be glued on to the outdrive with the 501x outdrives.
If my memory serves me right the 501 manual did not specify to do so.
