1969 Dodge Dart fenders swap directly with valiant fenders

The 73 and newer Dart fenders are the same shape as the 67-69 Dart fender. Marker lights are different, as is the headlight area, but yes, they can be installed with some modifications.
Valiant fenders are a whole different shape.
69 Dart Fenders are a one year deal because besides the side marker, they have the headlight set further up and back compared to 67-68 Dart.
That is awesome information. What modification will need to be done to fit a 73 on a 67 Dart. I know the side marker light is deleted on the 67. Can I just bolt my existing headlight bucket into the 73 or is their more fab work needed
