Because of the misfit between the starter, flywheel and bell housing I messed up the threads on the starter. I installed some M12 X 1.75 Time Serts to solve the problem. If you have never used these they work perfectly, if you have used them you know how good they are. They're expensive but they SOLVE the problem. It's hard to see in the picture but the new threaded holes are the insert that replaces the bad threads.
