Are there any differences beside the side marker light on the 72 up fenders. I know they are different in that way, but otherwise Im not sure. Thanks so much, Ken Michalik

I've used '75 4 door Valiant fenders on a '75 Duster and they were exactly the same as far as I could tell.

72 - 76 should all be the same I believe !

Other than the marker light, all the Duster/Valiant/Scamp fenders will interchange IIRC.

I've ran into an issue once where the rad cowl mounting points are different. It was on a 72 Duster trying to mount Scamp fenders I believe; its been a long time.

Okay, heres the breakdown.
1967 Valiant NO marker light hole
1968 Valiant Round marker light
1969 Valiant rectangular REFLECTOR
1970 and 1971 Valiant/Duster using a flush mount rectangular marker light. FIRST years using steel panel above grille
1972 Valiant/Duster New corporate marker light. LAST year for the upper steel panel to support grille.
1973 and 1974 Valiant/Duster same as 72 except without tabs to mount steele grille support panel.
1975 and 1976 Valiant/Duster same as 1974 except with different style antenna hole.

Didn't I talk to you about some fenders at CC @ Martin this year??

I dont know. I live in Northern CA and attend as many Mopar shows that I can in the state. Good luck with the car!

72 is a unique fender.

73 and early-74 (w/bracket mounted bumper) have a different headlight apron than the late-74 thru 75 (w/shock mounted bumper).

76 fenders are the same as the late-74 and 75 fenders with the exception of having a different antenna hole.
