Mini starter PLZZUZUZUZUZUZUZZZZZZZZZZZZZZZZZZ

My bracket racer starters have done this 3 times. It's a very high compression 360 and I've been using parts store starters, none of which has held up. I'm running a powerglide with a J.W. Wheel and I thought there were alignment issues, but after much checking, I found it's definitely the starters slipping. I am going to go with an aftermarket high torque starter.
