2015 vs 2018 front grill
Ya, except I mentioned all trucks after 99 look good with the Raptor grill. Last I checked, 2015 was after 1999. I haven't seen a Raptor style grill that looks good on trucks prior to 1999.
It’s not just the headlight though the bolt pattern for the ‘18 headlights are different so some/all of the headlight supports will be different as well. Some one here has done the swap I remember seeing a thread on it
