Strange Starter Problem

That's what I'm thinking now. The bolts are all tight and the dowel pins aligned. Well, pulled the trans off and the tq, the flexplate is on correctly, it has a stamp on it that says engine side only. I am going to buy a magnum starter and try that. Maybe the clutch on it is a little smaller..in fact i think the whole thing is a little smaller which I need to help clear some headers.
