1974 Duster Project

From the pics I have seen for that year of duster the bumper does stick out about an inch or so on the sides with a painted filler. As far as aligning it. Some times just tweaking the adjustment and splitting the difference will work. I cut my bumpers down on my charger I did not like how far they stuck out. but that take a lot of work and mine are powder coated so I was able to hide imperfections.Try raising it as high as you can on the left and lowering a little on the right.
