Another clutch not completely disengaging thread

How long does that nose have to be in order to accomodate t/o movement? Maybe shorten it?

Also "look around" and see if you can find a disk with a shorter spline hub, me? LOL I wouldnot be adverse to shortening that clutch hub "redneck" style!!

TO REPEAT..........I would certainly jig up the pp, flywheel and disk and check release distance/ figures/ clearance on a press.
