thinking if one was to stick with the "tab" type mounting system that maybe making it a single piece of steel wrapped around the rear cross bar and welded in place might be the ticket. Only thing about the belts wrapped around the bar is that they do have the capability to move side to side. I have a "hoop" welded on my cage to limit this movement, but it can still happen to a degree. What I want to improve upon is how my Jaz seat is mounted. I just can't see that those four 5/16 mounting points would do a whole lot of good.
