Starter Problem

Peter, car and truck transmissions are the same in the bellhousing area so that's not the problem. I can't tell a lot from the pics but it looks like the starter gear is engaging into the ring gear ok, but maybe it's the angle of the pic? Nothing looks terribly chewed up from what I see. I assume by your description that the starter grinds when you try to start it? Is that correct? Do you have a different starter to try? May be a bad drive on the starter. I assume the cables and battery are heavy enough?
