The one for the radio? WTF is a windon? If you're talking about the radio one, it's so the radio comes in better. If you aren't, it's not stock. The easiest way to get rid of a radio one is to go through the line in the trunk and unscrew about 3 or 4 screws and just take it out after unhooking some crap. Then you have to have a little piece of sheet metal welded in underneath, then use some body filler to clean it up.
