Welcome to the Nation!
As
@Reprise said yes it will swap over. If your buying the bumper cover new your going to need a few things. Fog light bezels, there is a grill at the lower part of the bumper aswell and the foam pad that goes between the actual bumper and cover.
If it's used get everything you can from the donor truck.
@dna59 did the swap, if you look through his posts you'll see all the differences there.
I attempted it but the freshly painted Denali bumper cover had an accident the day I was going to install. I'm going to get this done just not high up there on the todo list for me right now.
My Voy is a bit of a Jalopy. Its got Denali running boards, Saab roof rails, Ascendser tail lights, Avalanche third brake light, and a few other things. It's my build with stuff me and my wife like.
