But wouldn't u have to upgrade to the Shelby or 2013 gt front end? On a count that the head lights are slanted like the gt500 head lights and the stock 2011-2012 gt's are more rounded and oval than a slanted square
Sharktales over on S197 started this project but it turned into to much of a hassle. Not that it wasn't possible. I believe he is the 1st person to put a 2010+ front end on his 05+ and it looks sick. Haven't seen anyone else attempt it yet.
It is possible. I saw a thread on one of the forums that somebody did it--just don't recall which one (S197, ModdedMustangs?). The lights apparently bolted right in, but the wire harness needed some surgery. Sounded like a huge PITA.
