65-66 Dart Body Exchange

I just saw that VFN has fiberglass parts for the '66 Dart. I have a '66 Dart trunk lid that fits on my "65. Can I get a '66 bumper to bolt through the '65 valence and on the frame. This is for a track only car. I won't be using the parking lights. Will it fit the contours of the '65 or will there be modification needed? Thanks
