Not sure..as I'm about to try the same thing and install a tow package on my 2003 silver 3.0. etrailer.com has videos that show you step by step how to remove, install the receiver, modify the flashing underneath and replace the bumper. Check it out and see if it helps. Just enter your vehicle info and scroll down to find the videos.

Good Luck!
