Fairly sure there have been recent discussions on that. (about 6 months back) Write back if you do not find it in "search"
I found this thread in a quick search :http://www.concoursmustang.com/forum/index.php?topic=7881.msg55322#msg55322
Some pull the console with the radio in, I like to leave the radio in the car (pull the two nuts on the radio shaft) pull the front two screws on the side under the dash, the two above the radio, the 4 going into the floor and it differs for auto or maual around the shifter but once the top plate is off, self-expanatory.
Hope that helps
Richard
