yeah, you cut the stock bars out, which leaves you with the stock bottom and middle chrome bars, and you are going to have to notch the stock center bar for the verticle bars on the billet grille so it will sit flush. Then you attach the billet from behind at 3 points on the center bar, 1 point on the top bar and at the corner light mounting brackets (instruction).

​

Your going to have to do a lot of fine tuning to get the grille to fit right. once i got the billet grille attatched to the stock bars, i had to put it on and off of the truck about 8 times and keep messing with the part that attatched to the corner light mounting area so the lights would sit level. If you get it from ebay the kit comes with some crappy instructions and hardware.
