I would recommend removing the remaining bolt (jack under trans) or get a new one and try to test fit in the open hole to see if it will start to thread finger tight.
If the threads are indeed shot, you will need to drill out and Helicoil or Timesert the hole.
By the way, use the original Porsche bolt, not just a common M12 x 1.5 x 85. The
original bolt has a taper at the point to help guide it correctly.
A tip on inserting these big bolts, is to loosen the four small mount nuts so you can wiggle the mount to align the big bolts easier.
Good luck!

Thanks for this good bit of advice. I am going to R&R the 915 for a rebuild soon.
