I have a 2006 GC SXT and am trying to replace piece that houses the license plate lights and power handle. I have the piece removed, with the exception of the power handle. How do I remove this? It has to come apart to fit into the new piece and I don't want to break it while attempting to remove it. (I'm new to the do-it-yourself auto work, so I apologize for what is probably a stupidly-worded question.) Thanks.
