That's the front end found on all fullsize Jeeps until '91 with the original radiator grill, which was replaced several times over the years. The '88 grill is visible on the photo of my GW, which is an '89. It covers the openings for the 2 addtl. lights.
Everything else (bumpers, wood siding, etc) looks like it could be an '88 model.
Thanks Pioneer52. Every photo I have seen of a Wagoneer from the 70s & 80s shows the full-width grill like yours. Even Wikipedia shows the narrow grille on only the early 1960 models. Just looked like someone swapped the grille on the '88 I posted.
