I believe you posted this on adv and I replied that some early model skid plates will not work on the late models, at least without some modification. My 12 SW Motech plate would not clear the bigger cat converter on my 14 until I ground some off of the rear bracket. The SW Motech plates they are selling now have been redesigned to accept the larger cat. Also ACD has a new model for the 14+ models that will fit the late models with the larger cat. If you are considering moving an early model ACD plate to the later model, there will be clearance problems.
OTOH, the SW Motech luggage racks from my 12 fit perfectly on my 14 ES.
