mini starter install

I did happen to get pictures. all but one you can't see the interference. the only one visible is with the starter removed. however it wasn't like i was imagining. it actually looked ground down already. the problem was the post adaptor. popped the cap i didn't know it had to expose the nuts securing it. made it in to place and not sits flush and parallel. Adjusted the wires so the holes matched that of the adaptor and struggled to get them on the starter. haven't put the battery back to test it but I'm confident. thanks.
