Bumper swap

[l79m20]

I have a new body 07 with the black bumper on it that is in pretty rough shape. I want to change it out for a "new" to me bumper. My father in law bought a 14 and pulled the bumper for a custom built one for the farm. I got the bumper from him tonight but wont get the chance to see if it will bolt up for a couple weeks. My biggest question for this is if anyone has tried it and if it will work? The old black bumpers appear from the front to be 4 pcs, but after looking on the underside im fairly confident they are one piece with removable parts. The shape between the two look similar and I am thinking it will be fine. Any advice would be appreciated. The two pictures are from google and are not my trucks, just for reference.
