67-69 Barracuda Bumper on a 70-72 Duster

fyi 67-9 barracuda bumper is same front or rear, just different brackets. I could hold a 67-9 bcuda bumper up to my brothers 74 Duster if that is helpful. His bumper is on, but i guess it would check for width

That would help greatly. I'm mainly concerned about the width compared to the fenders and to get a better visualization of what I have in mind.
