Okay so I was taking off the B pillar for some work. went to put the bolt back in and rethreaded it. So I went to the dealership. they said I wold have to buy the whole seat belt. 107 bucks. not happening for one bolt. So i go to autozone and use that little bolt fitter thing. I think I have a match and M12 1.50 is the size I figured it was. I got the part for 96 cents. well get home and it is to big. so what is the seat belt bolt size. the one that is nearest your shoulder.
