This is one I bought from NY for my Dart. Off of a car that was wrecked early in its life and then towed to a junk yard. There it was forgotten about for decades and covered in a preserving coat of moss. Car's not ready for it yet so its up in the rafters, safe.
All LL, LH, and LM Darts use that grille paint schema, while the LP and LS Darts had black painted grilles except for two lines under the top and bottom sections (hard to explain) but there is a picture of a GT and GTS grille early in the post by kwhmopar1. The only difference in the bezels was the black paint applied to match the GT and GTS grilles (just around 1/2" of black).
