I have a 6 year old boy who is 4ft tall and over 60 lbs. I have been looking at the Corbeau Baja bench for the rear of the TJ so that I can put in a harness belt for him but Corbeau says that they don't recommend there harness belts for kids under 12, less than 100lbs and under 4'11". I was wondering if anyone has set up a 3 or 4 point harness for there kids in the rear seat. I am wondering if the harness belts would be to big for him. When we go wheeling I would like to be able to have a harness on him so he doesn't move around like he does with just the stock lap and shoulder belt with a booster.
