Don, it is 61 only parts. Also the station wagon rears are different. Car 2 and 4 door are the same for both 1 piece and 3 piece bumpers. Fronts are all the same for car and wagon.
It won't be one piece that goes all the way across the car, but rather 2 parts that fit on either side of the license plate panel. Hard to find good used ones. Ebay usually has a few sets listed. Also, VFN sells them in fiberglass.
