Only '73 & '74 Sports have the regular bumper brackets up front. They went to front AND rear shock absorber "5 mph" brackets in '75. (Rears started in '74.) As for the '73-'74 front reinforcement, if it was a race car, I'd say get rid of it for the weight. Otherwise keep it. It will help hold back any damage if there is ever a front end mishap.
Needless to say, I vote "keep the beak". Dusters are everywhere. I always liked Dodge styling over all the years and models and like being a little different anyway. Keep it what it is.
