Can someone tell me how to convert or modify the front and rear of a 2008 generation to look like a challenger?

or how to at least change the taillights in the back?

I have seen pics online of people who have done this but I dont know how?

 

They paid someone large piles of cash to do it for them......

 

How to convert? Pay someone a boatload of money. Change the tailights? Same answer. It will take a ton of fabrication. Consult a body shop.

 

Take Charger to Dealership, trade Charger, drive away with Challenger!!!

 

The body lines don't line up at all as is, it would require custom fab body work. Why would you want to?
