They only difference i can find in 74 vs 75 and 76 is the grille. The grille in 74 is flat vs the deep indicator lights on the 75 I like the 74 grille alot better than 75-76 I actually plan on using a 74 grille if I can find one reasonably. People probably think I'm crazy but 74-76 taillights and bumper treatment is my favorite of all the dart years. I just love the way the rear end in them look. If I was gonna make an ideal dart it would be a swinger body with 74-76 rearend and a 68-69 front end. Haha talk about crazy!!
