I think I’m talking myself into going with the 12.9. 14mm 2.00 bolt. I haven’t driven the car in over a month. Is this a mistake ands it’s going to bite me done the road? I appreciate the feed back.

If the differential is tapped M14 x 2.00, the only way to tap it to 1.50 mm pitch is to go larger (e.g. M16 x 1.50). As noted by Dominik, the 2.00 mm pitch has a smaller thread root diameter than the 1.50 mm, so you'd end up with partial threads that wouldn't hold. You'd have to go larger in order to have enough metal for the threads to hold.
You should probably stick with the M14 x 2.0 but, as eschaider wrote, find a bolt with a longer shank. I had to do that last year with a smaller bolt, and ended up buying a longer bolt to get the proper shank length, then cutting off the excess threads to get the length I needed. Not the easy route, but the proper way to do it.
