Hi all, I got my 1/8 gears (UE) from Mike today and the drive cups don't go through the wholes in the hybrids. Or i am not putting them togather right? And the diff. cup screw wholes are not threaded. Is this right or wrong?:C:
The diffs should fit those bulks just fine, as serum said. I have built 4 sets recently and they all worked perfectly fine with the UE diffs.
For the 6 spider diffs, simply turn the screws into the plastic cup. If the plastic cups were tapped, the screws wouldn't hold very well.
