You guys know the little plastic rivet that's on the seat belt shoulder strap that keeps the buckle from sliding down? Mine came off and now the buckle slides all the way down to in between the seat and the door. Real pain the ***. I know this isn't Isuzu specific, but somebody has had to have this happen before and has a solution. So I was wondering if any of you bright chaps has a good idea for something I can use instead or know if a replacement can be purchased.
