modify 73 dart fender for 1969

I am planning to attempt just the opposite. I have new AMD fenders for 69 Dart to use on my 73 Dart Sport. The fender shell looks and measures identical except for different marker light. Looks simple enough to remove that piece from each fender and weld back in the one I need. Once I get that done, I should have the 69 headlight mounting pieces as reproduced by AMD that I won't need. Just not going to get to that right away though.
