Copperone... I installed my top gun a month or so ago...install was painless. Fit and colormatch perfect. It will seem like you are taking a lot of the tail section out when you start cutting, but as long as you leave the "box" section intact(where your tool kit mounts), you really can't hurt anything, because the tail covers everything. Topgun sends little or no instructions, so go to the mods section here and print out the walkthrough link you will find there. Then hook up with Iceman for his really sweet led tailight units. I'm putting mine in this week.
Good luck and post up some pics.
