RE: Let's talk thread lock (and shimming)
You're over-thinking this. I've said already; shim it so that the shoes are completely covered, the clutchbell doesn't touch/rub the flywheel or clutch shoes, doesn't move in and out, and most importantly doesn't bind. If you have the right thickness shims, you should have no issue shimming the bell to have zero play and not bind. No play does NOT mean it will bind. There is too little, too much, and just right.
