I have a 2001 ML320 and the left backseat seatbelt is missing the bolt to the bulkhead (left of the seat by the door). Looking at the right side, it appears to be a round-star shape bolt head but can't seem to find what size it is. Does anybody know where I could find such information or recommend what bolt to use as a replacement?
** Forgot to mention it was the anchor bolt and it appears to be 7/16 (not sure). It comes form above and anchors at the seat level.
