don't mean to hijack your thread shawner, but I figure the addition of a thread is not necessary.
kdub, my GT2 went together pretty well, but my only concern is with the diff.
With all the gears in the transmission and the halves screwed together, the diff moves a lot side to side, in the case. Is this normal? I've never seen it before so I just assume to shim it a little bit. It doesn't affect the tranny at all, I'm just worried about it catching a tooth wrong and stripping the whole gear.
Oh, the posi-lock system is stupid fast, you guys did great on that one!
