Differences between 70-72 and 73-75 dusters

lotts of people change out to the early style front clips/tail pannels/deck lids the structure of the car is the same aside from the floor pans being tweaked due to cat systems if you go with a 70-72 duster the interiors are diffrent you would need doors and rear metal sail pannels 73-76 duster interiors are all the same and you would need to change the side marker lenses on the out side of the car if you want a 70 or 71 duster since they are flush with the body in those years
