65 Dart fenders are 1 year only. However; if you use the complete front clip from a 64 or 66 Dart or 64 thru 66 Valiant or Barracuda, that will also bolt right on with all the body lines lining up perfectly. 2 door posts from either Dodge or Plymouth will also work.
Except for mouldings and trim, the '64 and '65 A-body 2dr sedan doors will interchange and look the same. '63 won't work due to different latch assy's. '66 started the modern lock cylinders so it would look different but should fit OK. You might have to include the hinges as they changed that year also.
