Take your pick. I think any of them would work.

I pulled out all my starters about 10 and discovered that there are differences in the bell housing mounts. two of them had 2 bolt mounts and one was a 3 bolt mount which was smaller . I have a body with out a nose cone mounted that had come with an aluminum two bolt cone so I tried to put the small 3 bolt bell housing on that body and I had some trouble but it appears that it will fit.
There is a small dowel pin on the starter body that matches a hole in the nose cone and the cone has a ridge that goes into the starter body. Then the two long starter body bolts screw into the nose cone. I need to clean up some corrosion on the two pieces but it appears that they will go together.
It was late so I didn't have time to get into it so I will check today and report what I find.
