If you were to take off the bumper & grill off the 09-11 fx as one piece and replace it with the 12' it will/should bolt right up. Willing to bet it will. There not going to change the looks/shape of the hood and fender just for the front end when there is no need to. All they did was redesign the front bumper & grill that will bolt up on the 09-11 for a inexpensive update.
