1973 Dart grille into a 1975 dart?

It's been a while since I did it, but I went '75 grill into a '74.:
1) You'll need the corresponding headlight trim.
2) You'll need to tuck the bumper in. The '75 has a filler.
3) I believe it's a tight fit for the parking light plugs from '74 to '75 grille. Should have plenty of room the other way.
4) Don't remember if there are any extra used/unused attachment points.)
