I'm in but will have to stick with lap and shoulder belts. I use the rear seat for passengers every so often, so putting in the bar behind the front seats to secure the top straps of a 5 point harness won't work for me. I already have 2 fire extinguishers in the jeep (still need to mount the second) - please check if type BC is ok (good for fluids and electic, but not regular combustible solids). I have a grab handle on the passenger side door bar already, would need to know if/what extra handles are needed.
