I have probably called 100 + junk yard between Houston , Dallas and Austin with no luck and one idiot that sent me on a wild goose chase that ended up being a cop car. He was so adamant that it was the same bumper and that not all SRT8's come with a special. Clueless liar.
Saw a nice 2008 SRT8 at a Budget Auto Parts in Auburndale, FL earlier this week. It didn't have the engine, transmission or seats, but I think it was otherwise fairly complete. You may want to give them a call to see if they have what you need. 800-282-5581 ask for Jim
