Bench seat hinge covers

68 sedan. Look at my thread on the 70 swinger interior upgrade. I have a 73 seat in the front. The hinge covers are the same as the ones that 72demon has pictured and they are the ones. See that square hole on the hinge metal. A plastic piece fits in there much like the license plate plastic pieces do for the license plate screws and the screw goes into the plastic piece and holds the cover on the hinge there. The cover also is held in on the bottom by the seat covering material. See my thread for reference. Any bench seat 73 up should net you the plastic pieces and mounting screws along with the hinge covers as well. You could put a post on parts wanted and surely get the stuff you need. Good luck!!
