Virtually certain it will fit since the sheet metal does not appear to have changed (and Ford would have avoided that, to save on the retooling costs). However your tail lights are larger and have a different shape than the 2013s, and will interfere with the bumper cover fit unless you change those, too -- and those new tail lights are VERY expensive, according to people who have priced them. (Can't recall the exact figure ... $800 each? Something like that.)
Have you considered painting the black plastic parts to match the body, like the 2013s are done? That would be a lot cheaper.
