The fenders will work, the only difference is GMC has the parking lights in the fender. The hood is different, the bumper is the same but the valence is different. The front crossmember is different. The doors, cab, running boards, most of the interior are the same. Outside of the few body panels and the engine, there are few differences. There may be some others that i did not mention but I am sure the GMC guys will let us know! grin
