Counting up all the things to order while i have it off for a new TO Bearing.

I found this. The stud pulled right out. Thoughts on repair?

As the flywheel is machined the pressure plate sits deeper into the flywheel and moves away from the throw out arm. This changes the geometry between the throw out arm and pressure plate and transmission case. Shimming the ball moves the throw out arm toward the pressure plat again, correcting the geometry.
So you really only need to shim the ball that same amount as is removed from the flywheel.
When Trans is installed the throw out arm should be pushed by the throw out bearing/pressure plate most of the way forward in the opening in the bell housing. If the flywheel is machined and the ball not shimmed the throw out arm runs out of travel when the clutch cable pulls on it because it hit the back of the opening in the bell housing.

I don' recall seeing any measurements or specification for the ball height.
The 6 flywheel spec work for the 4 flywheel as well.
Machine shops should know this but not all do, the surface that the pressure plate bolts up to has to be machined the same amount as the wear surface of the flywheel to keep the pressure plate working correctly.
