Hello, I have a 1994 Ranger Extended cab and I'm having issues with the passenger side seat belt. A couple of my buddies are fairly big dudes and they're complaining that the passenger side belt doesn't extend all the way. My question is a) What might be wrong with the belt and b) How do I get to the seat belt assembly to check it out. It is the two door and does not have the pop out rear windows. Any and all help would be greatly appreciated. Thanks in advance, Art.
