Here is a pic of my jacked up 2: http://img182.imageshack.us/img182/6701/rear2fi2.jpg Now on the support there are a couple of metal pupports that come out, then that plastic thing connects to that. Now does the metal things holding it on come out too? They seem connected inside almost above the muffler.
