Just noticed this the other day! On the driver's side where the back of the seat is hinged to the bottom of the seat, the plastic cover has come apart and won't go back together. I consider myself pretty good at fixing anything but I can't get this thing back together. Also on the outside of this cover you can see an impresssion where they are bolted together. It's a 3/8 inch circle in the plastic. Has anyone had this problem?
