No groove in the yoke and I'm not sure if the bushing has been replaced. I had someone rebuild it but who knows if they replaced that bushing. Just by feel, I can't feel slop in the yoke. And how do you check radial clearance? Mag. base dial indicator on the tail housing and try to shake the yoke? .0025 in not alot about the thickness of a piece of paper.
