72 Swinger headlights

the plug holds the grille. Looks like your bumper has been TWEAKED. there is usually 1" of space between the the grille for the bezel to slide out. a side view photo of the bumper will show the placement of the correct location of the bumper in relation to the fender and there by match the grille.
very weak design for the bumper by Dodge so the bumper brackets move in even though no physical damage
