Bumper differences from 2007-09 to 2010-13

This morning on the way to work, the car in front of me swerved to the next lane and I immediately saw a small tree branch, too late to avoid it so it hit the valance at the bottom of my bumper. Here's the damage (note: the part that looks like a dent is my reflection in the bumper, not actually dented).





My question is, has anyone here put the valance from a 2010-13 on their pre-facelift 2007-09 truck? It's only a subtle difference, but I do think it's a nicer look, so if it will bolt up with no issues I want to get the '10-13 valance.

Other note: the ground is wet because it was a rainy night and also off-and-on this morning...not anything coming from the radiator. It was fine.

 

The parts diagram on SparksParts shows the valance in the diagram for the steel bumper but does not list a part number. It does show a valance part number for the resin bumper. I don't know what the difference is between the resin and the steel bumper, but it does only show it fitting from the 2010-2013.
