All I can say is the top bolt was a ***** with the old starter, I got it out and sat the starter on the C-Link. Crawled out from under the car , turned the wheel all the way to the pass side and bingo the sweet sound of the pig hitting the floor. The mini went in like a hotdog down a hallway. I do suggest you get a 5/8 half moon or Cwrench. it makes that top bolt a lot easier to tighten. I got a whole set for 12.99.
