I have a 75 duster that needs a fender. What all years/makes will fit. Will any dart 4 door fenders work.looking for a direct replacement.

1967-76 Valiant and Duster used the same external stamping for the fenders, but there were changes.
67 had no side marker.
68 had a round lighted marker.
69 had a reflector
70-71 had a flush mounted, lighted, rectangular marker.
72-76 used the corporate marker light.
The most correct fender would be from any Valiant/Duster from 1973-76. The 1976 fenders used a different antenna, so the hole through the fender is different.

Your Duster is a "PLYMOUTH". a Dart is a "DODGE". They wont match. You need a 73/75 "PLYMOUTH" Duster fender..

With the 67-76 A body cars, it is easy to think that they may interchange since the body lines appear identical. The Dodge has a much different slope at the rear of the wheel opening. The Dodge fenders are a tad bit longer at the leading edge too.

Will 4 door valiant fenders work
