My project is coming to a close soon and I need to finish off the interior. I'd like to not drill the body for re-installing the harnesses.

4 point. The two for the rear mount to the rear seat belt points - easy. The outboard bolts mount great to the old stock hoop points. Luckily they are all the same bolt size and thread.

So where have you installed the inboard bolts? I used to have a hole drill behind the seats in the floor. Filled that up (welded) since it would grind over large speed humps.

The inboard seat points are two bolts each - tough. Drill a hole in the seat bracket?

Where have you mounted the inboard harness points?
