Thanks. I ordered and received a new starter 5035102AB. Later model, not sure the difference. All the rest of the parts are ordered as well. The problem now is the driveshaft. I need to know the exact difference in length between the Nag1 and the HP70 from the bellhousing to the driveshaft mounting surface to get one made in advance. I have a Ford 8.8 differential so it will be unconventional, and will need a CV on the front side for a little give.
