The difference between the 2 valances - 2wd is 4 3/8" wide, 4wd is 7 1/2" wide.

I bought from my local dealer, the box is ridiculously huge so the shipping was outrageous from anyone online. I don't have the receipt easily accessible to pull the part number, just let them know you want the valance from the 2wd, same year of your truck.

Installation was easy once I figured out you have to push the center of the plug out to pop it out, other than that, a few screws and it's done.
