Need Help! Front Bumper Identification (pictures)

Agreed. My grille is in the attic and I don't feel like digging it out. Also, the bumper backing panel fit alright, but not quite perfect.

Another thing I noticed was that the bumper I have seems to be taller on the top half (where it bumps out more) than a 73 Swinger's front bumper should be. On the photo of an earlier Swinger's bumper, it looks like there is more surface area below the bump-out, as opposed to the later (valiant) bumper, which is split ~50/50.
