you would need a bar behind the seats as the shoulder belts are suppost to mount at or below your shoulder blades.
seriously, if you think you are gonna wheel hard enough to roll over
you should wear a helmet. there is no joke here!

LOL, if you are a taller person, like me, you would think about that seriously if rock crawling or if you're doing some risky behaviors. On a roll over your neck stretches, your back stretches and your seat belt stretchs so you head gets mighty close to the outer edges of the roll bars.
If not that then rocks sometimes purposely avoid the roll bars and come inside to say, "HI!", and boy does that hurt really bad.

I would check that info. The shoulder harness is supposed to prevent forward motion, not hold you down to the seat; the lap portion of the belt is supposed to hold you down. If the sholder harness turns down sharp at your sholder you will get spinal compression(bad thing) during roll. I know you can angle the straps down but there is a limit on how much. The Corbeau belts I installed on my Bronco had the mount locations with them, the paperwork has long since been circle filed.

The shoulder harness bar is not supposed to be at or below the shoulder blades as suggested above. It is supposed to be at or just above the collar bone height to prevent spinal compression in an impact. Also, the harness should be attached to a rigid point like the existing seat belt points, and not solely to the bar since it can bend in an impact (if you are going to use one of the few DOT approved 4 point harnesses on the street). If the harness is just for keeping your butt in the seat while crawling, then bar placement and attachment points are a bit less important.
