yup, you can use your fenders, just need to fab up them tabs.
you will need a grill, a 69 valiant grille will fit (thats what i put in my 72 duster) a standard duster grill will work and also the more sought after and expensive duster shark tooth grill will fit.
you can use a bumper from a 70-72 duster....and Im not 100% but i think a valiant and scamp from those years also has the bumper you would need.
and you will need a hood from a 70-72 duster some valiants and scamps also have the hood you need.
other than that I think you also need the filler panel.
