the t/o bearing have 0,7" of stroke and the clutch only need about 0,5" so it doesnt need to be perfect. Shim it to about 0,01-0,02" clearence. The enalrgening of the id is not neccesary cause i neede to shim it so much the bearing is of the bearing retainer. I just did it to make marking and drilling the holes in the bell very easy (same id as bell)
