Rear plastic filler wanted....

....for the 74 duster. It's the piece that goes between the body and the rear bumper. There are three pieces to it. The main center section that runs from side to side and then there are two end pieces. I need the two end pieces with the mounting screws. I'm in West Plains, Mo. 65775. I believe that the same pieces from a 73/75/ or 76 will work.
Thanks guys.

i have all 3 pieces the center is shrunk down a little $80 plus shipping for all 3 pieces(its also been painted blue)
