Its all one piece.
you will need a phillips screw driver and a 10mm socket.
first you need to remove the marker lights. Remove the big plastic shield. Two 10 mm bolts and four plastic phillips push pins. Then two phillips per marker light. Pop thoes out. Behind those marker lights are two screws. Remove them. From memory I dont thinkt here are any more screws on top but I think there might be. If there is remove them, if there is not,,,,, well carry on then.
All the screws out, the last step is the fun one. The bottom of the grill is snaped in in four locations. To the out side edge of each head light, and directly beneath the vertical portion of the grill, to the inside of the head light.
ONE AT A TIME gently but firmly pull out where these snaps are. I reccomend doing the two out side ones first. Then the two inside..
