I'm confused which holes for the diverter were stripped?
The top pin, that was previously your tiller arm pin, does not get used. Instead a short one with a 5/16 threaded hole gets put in. The lower pin gets reused. Make sure you use new nylon bushings.
The hole on the trim arm is either oblong, for a hydraulic or circle for a manual.
The the cable that you have now, what diameter is it?
