After 12 years of use, the bottom half of my seat has broken. The metal has sheared in half around the bolt holes that the seat back attaches to and will no longer support weight against it. A poodle could even push the seat back down..... Every place i've looked online gives me the seat tracks, seat belts, etc but not the bottom seat frame that i need. Anyone know where i can find one? other than going to a scrap yard and finding a good one?
