center drive shaft a little short

[Urgeoner]

right on mag I just needed to see if it was ok for some play..that rhymes
you're using the 3905 transmission also, right? I have the v3's as well and I'm using the UE 6mm transmission cups, but the ID's aren't slotted;the just use two set screws to hold the shafts so I made sure that it it really tight w/threadlocker...good luck with your situation though.
