Will the fenders, header panel, headlights, grille, and bumper from a '92-'96 F150 fit on a '86 F350?

 

I believe you would need the core support, hood, and piece below the windshield as well.

Yes, if you get EVERY piece of painted sheet metal forward of the w/s, but the bumper will be a challenge since it mounts TOTALLY differently. And the front wheel arches won't match the rear, unless you also change the bed.
