someone on here had actually done that with a stock front bumper, and they said that the sides weren't quite long enough.
TTT I had to trim two little square holes in the "dips" of the front bumper and then it went right in, it fits a little tight, and I also had to screw some self taps through the fender and bumper to get the sides to stay up, but you can't see them at all. I want to nut and bolt them with washers eventually, because I am afraid that they might pull through the thin metal. it was actually easier than I had thought. I love the way it looks, especially the black on blue.
