833 Transmission won't disengage at stop after 100 miles.

The pressure plate is very obviously engaging crooked. With heavy wear on only one of the three arms, that's pretty obvious. Either the pressure plate cover is bent, or the pressure plate arms are not equidistant heights off the flywheel with the pressure plate bolted down. You should measure the distance from the flywheel to the arm ends where the throw out bearing makes contact. I believe you will find some discrepancy and that could also be the problem of not disengaging the clutch enough. From the pictures you've posted so far, that's my only explanation.
