Looking for a used or take of rear bumper

[Niner]

Looking to buy a 07 Grand Prix. Only thing wrong with it is the rear bumper is trashed. My buddies with Mustangs are always talking about new take off parts that are great deals. Can you find these for Grand Prixs anywhere. Exactly what are they? Any help would be great.

My buddy with a mustang pointed me to these guys. OEM Parts & OEM Wheels - Original Equipment Parts from NewTakeOff
It looks like they do mostly Mustang stuff. They do have GP rear bumpers though.

Has anyone dealt with them before?
