That harness attach bracket Dave had was totally bogus. That bracket weld, which IMO looked pretty bad, was pure tension in a head on wreck. It failed. Todd Bevis built my Demon with a 3/8" ID tube welded vertically through the center of the cross bar, that a 3/8 dia aircraft bolt which attaches the harness tab goes through. No way that will ever fail. The belt will cut itself in two at the tab first IMO. I like that way of attaching the shoulder straps over wrapping the belt around the cross bar.
