Bolt in Harness Bar don't do it!!!

Mowry, couple of questions for you:

Are those Schroth ASM belts?

It appears that you have a notchback and the belts are plenty long enough, could you weld up a structure in your trunk under the tray and attach the belts to that? It would be unobtrusive to the rear passengers and you could spread the load along several structural members in the trunk.

Another possible option would be to anchor the belts to the floor and use the harness bar for positioning the belts at the right height. I know they would still see a pretty good loading in case of an accident but it should be somewhat less than having the belts anchored to the bar itself.

I understand what you are trying to do, I have the same problem in a 67 fastback so no place to hide the bar. Car will be driven on the street with my kids in it so a cage is not an option, but I will be autocrossing the car so I would like to have something. I have raced cars before and did my best to knock down the front stretch wall once (it's still standing despite mine and numerous others attempts) so I do know the value of a well built cage, a proper seat, and a 6 point harness. From what I have read the Schroth ASM system is designed as a 4 point but collapses like a 3 point. It also is designed to be mounted using the rear seat belt attachment points. While nothing is perfect short of building 2 seperate cars (not in my budget) it will be a definite improvement over my lap only set up that the car had before I started building it.
