Agreed, the angles for the lap belt position are important. The installation instructions from Wesco pretty much just talk about using the factory mount points, but I've looked at other brand sites and their install instructions and I'm making sure the angles are going to be good.

The upper pivot mount in the pillar uses a backing plate which I will fit inside the pillar. That will be loaded mostly in shear which makes me feel a bit better about the relatively thin sheetmetal in the pillar. I've seen people just weld or bolt it to the outside of the pillar which leaves a lot of strength out of the installation.

There are Federal Aviation Administration approved shoulder harness install kits available which literally just attach to an aluminum rivnut installed in a spar section using a 3/16" AN bolt. Now THAT is a joke, moral support only.
