trailer hitch for a early dart

JC Whitney used to sell one years ago for a 64 Valiant where you took off the rear bumper and then replaced the two inner bumper brackets with ones in the kit that had tabs welded to them. The hitch then bolted across the inner bumper brackets. The bumper got reinstalled and two little brackets went up to the license plate light holes in the bumper which helped to keep the hitch from flexing.
