I've recently upgraded my differentials with the traxxas brand spools and tonight I tried install traxxas brand steel driveshafts after the stock ones broke but the cup that goes over the spool ends does not fit. I tried sliding the new driveshafts over the old differential output shafts and they go right on. Obviously the problem is with the spools but doesn't make since. Has anyone else ran into this problem? Any easy fix? I would understand it they were aftermarket parts but they are alboth traxxas brand parts

this is the cup that doesn't fit onto the spool
this the spool comming out of the differential housing.
this is how far the drivrshaft cup will slide into the spool. Barely slides on at all.
here is a picture from the bottom showing how much farther it needs to go on. The set screw hole should be lined up with the cut out in the bulkhead to get the screws in and out
and here it is fully slid on the the orriginal differential that was removed from the e maxx
