You'll need to pull it as far forward as you can to get at the bolts, my grill is simple to remove, "pop" the clips at the top with a flat screw driver blade and lever forward from the top and the bottom clips will "pop". Hopefully you don't have wires/cables running through the grill (driving light wiring or CB antenna cable), if you do then you will have fun

Just a note, removing and re installing the lights this way does not effect their adjustment.
