'73-'76 Dart Fenders on a '67??

My 67 Dart came with 73 up doors and fenders. No vents in the windows and the fenders seem fine. You will have to play with the headlight pots possibly but other than the marker lights..they are the same..67 to 70 and 73 to 76..I believe 71 and 72 had the fender ext. ?
