The rear won't work... tried that. The lights use a completely different wiring setup then 08-14 cars.

Also with the front, the hood needs to be changed as well I've seen. As well as the front facia and other bits and pieces.

All Hellcats have 2015 tail lights and completely unique front ends. It might look like 08-14 grilles and such. But nothing is the same. Everything is unique to the hellcat facia.
