73/68 dart sport.
The proper way to eliminate picnic bench bumper is to just move it back using the older brackets. I think the beak on the car looks pretty cool if the Bumper is place where it was original meant to be . The 5 MPH law changed the appearance that was intended . The same with the Duster as The Dart. Check the pics below.
If you wanted a 68 you should have bought a 68. I personally am not to fond of the appearance.
