Just to confirm for everyone, the sleeve is out of the arm. I need to confirm with Peter Bergman
@GMachineDartGT whether the delrin bushings are supposed to press into the arm and then the shaft rotates in the ID of the bushing. One bushing slides on and off the shaft by hand, the other was a press fit on the shaft. If the new bushing is supposed to press in the arm, then I think I'd be fine removing the high spots so it doesn't damage the bushing and pressing it in.
