Recently noticed that when I shift out of park there is a gaping hole behind the shifter handle. Apparently there is a plastic panel that should float behind the shift handle (never noticed before) which has suddenly broken. Does anyone know the part description and/or how to repair? I have a 2005 model. So far I have only seen the "accordion type" vinyl shift boots, and mine is nothing like that. More like front and rear base panels, and the rear one is broken.
