Clutch release arm

You may have a too-short fork-pivot bracket. Are you also almost out of adjustment on your linkage?
Notice in FOGs post, the TO fork is more to the front of the window,when at rest? Yours should be like that, perhaps even more to the front of the car. The only way to achieve that is with a taller pivot, or a a different TO bearing collar.If your pivot is too short, then the outer end of the fork moves to the back of the car, and the geometry gets all messed up.
The same thing can occur if the clutch disc is too thick. The diaphragm fingers move forward and the fork follows.
Also, if the thrust bearing inside the engine is banged out, the fork follows.
Also if the scattershield is too deep or the block-plate is too thick, or the flywheel is too thin.
Perhaps the solution will be to space the flywheel back, or to space the fork-pivot forward.
You can't have the fork hitting the opening in the scattershield; it will only get worse as the disc wears thinner.
