correct to the above, nothing on the rear is interchangeable... just take a look at the two they are completely different. tail lights, bumpers, hatch, etc etc etc
if you do a quick search you will find your answer because this has only be answered many different ways. I personally really want the REbelDevils rear bumper. or go custom exhaust and do a SE lower valance.
The rears of the cars are entirely different, The taillights, bumper, hatch and even the pocket for the taillights in the body are different. There is another thread about doing a 13-14 to 15+ conversion, and rebel devil customs came in and confirmed that unless you modify the taillight pocket to fit, it is not possible to actually change the rear of the car.
Sorry to burst your bubble, but it won't work without lots of time, modification and money...
