At the very least you are going to need to swap headlight bezels, grille and tail lights. They might let you get away with ignoring the trim but even that is a little dicey. The rules aren't heavily enforced anymore but you can't just totally ignore the major pieces like this. Do bear in mind that those pieces are not available in reproduction so you're talking a pretty expensive swap to change years on a Fairlane.
