Well if I remember right the roll bars and seatbelts are both 3/8's grade 8. When I rebuilt my B-pillers (85 CJ), I had the skin off the outside and welded in 7/16 nuts after fixing the pillar its self. Then I welded in the new sheet metal panels.Originally Posted by grignac48
After doing all that, I too went with a 4-point harness, but still have the stock belts just in case VDOT doesn't think the 4-point is safe (wouldn't surprise me)
