That angle goes away the closer the clutch leg gets to override switch
I welded a small piece of flat metal to end of a bolt so that piece fit the width of switch and at the right angle.
It is important to adjust seat distance before doing a final tweak of stop length
Testing and adjusting is needed.
I did some testing today and needed to adjust stop just a tad shorter for shifting is fine at low speeds but at high RPMs the pressure plate has some centrifugal force and stop needed to be just a bit shorter to assure good shifting at high engine loads.
