I'm pretty sure the "beak" is different from 73/4 to 75/6.
Also the lower grille mount is specific to 73/4 and 75/6
I had to replace some pieces on this 75 dart and at first I had 73 pieces and side by side, they were different. I had to hunt down the 75/6 specific pieces.
Just an FYI so you can look for 75/6 pieces for a more successful swap.
Its snowing here but this week if you need side by side pics, I can help because I have this 75 dart and a 74 dart sport.
