73 duster dual snorkel

73 bolts on 70 71 with no mods. to bolt it on a 73 -75 you will need to ad two washers under the middle stud and fill the small area that is recessed for the beak on a dart hood. Very Easy mod if you know what you are doing. You can't really see the difference without looking for it so it could be left as is but the washers must be added . I will explain when you call if interested
