From a cosmetic standpoint it appears the front stake pockets are a couple of inches shorter to accommodate the different step design. I'd like to see more of these fenders on our trucks, to me they fit the cab better. Here's a picture of the first truck I'd seen with the swap, back in the late 70's or early 80's. It was a former show truck laden with chrome, and was very striking in person. It looked much better than the photo shows.
