Trying to understand these front seat belts.

Mystery of the short seat belt solved. I measured the drivers side shoulder belt, then the passenger side belt and found out that the drivers side was 10" shorter than the passenger side shoulder belt. I took the drivers side seat belts out and went to a auto interior business that is close to me to have them re-strap the shoulder belt. The guy called me and told me that at one time the belt was ripped and someone just cut out the ripped part, looped the other end around the buckle and sowed it back together. Now that it has been re-strapped it fit's just fine.
