No, the 73 and 4 charger fenders will bolt on, but have a bigger wheel well opening. The wheel lip mouldings would be too small from 71/2 to 73/4. You can modify a 72 to fit it though.

Restoring a car to look "only" as good as the factory made it is like getting a boob job for your wife and having the doctor make them two different sizes to seem more natural
