I know the part numbers are different but I'm unable to find if 73/74 has been superseded. I only have 74 parts book to compare. They look the same but there might be a slight difference that I'm missing? Any help is appreciated.
Headlight Bezel 73-74 part numbers 3672188 and 3672189 do not supersede to a newer number.
Headlight Bezel 75-76 part numbers 3781286 and 3781287 do not supersede to a newer number.
Must be some difference between 73-74 and 75-76 Bezels.
Another difference between the years is that '73/'74 had a thin chrome strip across the nose of the hood. '75/'76 had a taller chrome strip that made room for "DODGE" lettering to be formed into it.
Dusters and their respective notchback siblings went through similar styling changes between the same years.
Not too much trouble swapping between the years. Just gotta keep the OEM "set" together. The extended "shock absorber" bracket bumpers on '75/'76 models would be the biggest problem to overcome.
Same for the Plymouth Duster, Valiant and Scamp between 73/74 and 75/76.
You can install a 73/74 grille and headlight bezels on a 75/76 but cannot do the opposite unless you also install a 75/76 lower panel support on the 73/74.
I'm looking at replacing whole set up(grille/bezels/trim) NOS very few and pricey. I'm looking at OEM but the whole set up(1974 Dart Sport) isn't available until June July from there website. Thanks for info guys.
