As you know, you need the engine shaft center to starter shaft center to be the same as it would be in the original position. Be careful because I seem to recall that I determined that either the starter shaft centerline is not in the center of the hole in the plate for the 'nose' of the starter housing, and/or that the center of the starter shaft is not exactly on a line connecting the two starter mounting bolts. I measured everything as carefully as possible; then center-punched where the new hole in the plate needed to be, and had a machinist friend put in the hole. I drilled the new hole in the starter mounting flange myself. Things lined up very well. If need be, you can oversize the new mounting hole a bit so you can adjust the mesh before tightening down the bolts.
