See attached file from 2007 Service Manual. Can't remember if you have to remove the tail lamp assembly. Once the access panel is removed (I think it's just held in with tabs; move it side-to-side to remove it; might be up-or-down; can't exactly remember), you may be able to just remove the socket of the bulb you need to change & then re-insert it into the tail lamp assembly after swapping bulbs. Keeps you from possibly damaging the seal for the tail lamp assembly.

You probably need to download a copy of the Service Manual in the Crossfire Documentation Collection. Either the 2004 or 2005 will do for an NA Coupe. You need the 2005 for a Roadster & SRT-6. Most folks download the 2005 version which gets you both Coupe & Roadster covering the NA & SRT-6 models..
