Eliminate rear bumper rubber filler on a 74 Duster

The 1973 models used the same size rear bumper as the 70-72 but often had the added bumper guards bolted to them.

For my 1974 "FrankenDuster", I welded sheet metal plates across the huge holes in the rear frame/crossmember that were originally there to allow the 5 mph shock absorber to pass through. I then simply used an AMD bumper for a 70 Duster and 70-73 brackets. The front also had the 5 mph bumper. I switched to a 70-72 hood, grille and bumper up front so to mount the traditional bumper brackets, I made my own sheet metal plates with captive nuts welded to them and slid them inside the frame rails. There seems to still be more 73-76 Dusters and Dart Sports around compared to the more desireable 70-72 models . I'm glad that it is so easy to "back date" the cheaper & more abundant cars.
