Rear Bumper Replacement

I’m trying to figure out what year models will be compatible with mine. I have a 2007 and need to replace to bumper. What year models should I be looking at? I’ve found a 2004 but want to make sure it’s compatible before I purchase.

 

2006-2009 were the same bumper covers. Previous years were a 3 piece design and are shaped different with different flares

 

Has anyone tried to put the 2006-2009 bumper on a 2003-2005? Does it fit/have same alignment lines, gaps, spacing? I'm asking because I've beat the shit out of my rear bumper, and it has those ugly useless reflector housings.

I put '06 tail lights in my '05 as one of my first mods, and it's probably my favorite to this day.

 

Just going on what I know. It will all bolt up. But, the fender flares won’t match up. If you look at the fender wells, the shape of the actual wheel well and the flares are different. The 06-09 is a rounded wheel well with bigger rounded flares.
