I never noticed until I replaced my header panel. The one on there was from a 93-95 grand cherokee, and it being a 97 I replaced it with one for 96-98. Once I got the new one one I didn't realize my old grill didn't fit. If you notice also the later model grills go below the line of the headlights into the bumper cover whereas the earlier model is in line with the headlights.
