I wouldn't bother with Jacks. I tried ordering a grille badge from them. I hear nothing back from them. Almost three months later, I finally get an e-mail saying they have the part in stock and asking if I still wanted it. I immediately e-mail back saying yes. That was three weeks ago. I've yet to see any badge or hear anything from them.
I'd previously ordered stuff from the place listed below and actually got what I wanted. The only reason I didn't try getting the grille badge from them is that they don't offer it (it needs to have the pins to put through the grille).

Another thing to keep in mind, Fatcat: The new Challenger is considerably larger than the 1970s models. Hence, the side badges that are designed for the 70s Challengers appear too small on the modern cars. That's why I didn't put mine on my 09 and instead went with the side stripe with the word Challenger in script. That came from RiderGraphix.
