unless you have it on there yourself without the midnight edition bumper then no telling, I suspect some trimming would be needed of some form (to the valance)That is actually INCORRECT.
If you look at the front bumper of the z71 edition, you will see that the chrome piece you see from the front view is a part GM is calling the "VALENCE"
That valence IS specific to the z71 front bumper (hence the z71 advertised special front fascia)
However, the SKID plate mounts below and behind the bumper...I don't think it really matters what trim level you have.
If you look at my post #21 in this thread, you will see my the photo of my fingers sticking up between the skid plate and the front bumper.
mechanically it "should" bolt up. I could be wrong I haven't tried it just looked at a lot (available) photos in the past.
I don't recall if the front bolts require the specific front bumper or not, the front bolt holes are recessed on the skid plate.
a couple more angles of that plate
