Duster rear bumper question

I agree with you it looks lousy.
I just went out and measured mine (its a 73) and the body extends 3/4" below the bumper. The best I can figure they took an older bumper and stuck it on to replace the slightly larger ralph nader version. Also one side looks slightly cocked outward from the pictures. Also the rear shot shows the top gap to be tight at the outside and more open in the center, the oppisite of mine.
