Re: Bottom bumper chrome
this is the how-to for 08+. http://jeepgarage.org/showthread.php?t=2679
You would probably need to drill to insert the chrome strip in. From the looks of the 07, i think you may have to remove the bumper cover to do it (not too sure), unlike the 08+, you wold need to remove the lower bumper lip.
