75/76 Duster Grille in a '73?

I did the conversion on a Duster and did the same on my Dart Sport. I don't recall what any minor mods were, or if any were needed. Parking light sockets were a tight fit on one, but forgot which. I believe you have to loose the plastic bumper filler that's attached to the grille? The Duster was about 10 years ago.

A '75/'76 grille needs '75/'76 headlight bezels.
