I installed an RXT and a 26 spline along with new TOB, TOB Retainer sleeve, and Pilot bearing. I shimmed the 26 spline and had 0 movement. I've only put about 60 miles on it so far as well so maybe it's normal. But here is what I'm hearing. Everything seems to drive fine and I don't get too much clutch chatter. But let's say I'm slowing down for a turn and I go from 3rd to 2nd. I hear a higher pitched whine when I try to down shift. It goes into gear just fine. Doesn't do this when it's in neutral, only in gear while rolling. Also I have cobra bob gaskets, but I didn't replace them when I did the clutch. So maybe they need to be replaced, I wasn't sure if they were reusable.
