It seems that the part number (PT93353100WS and PT933-53100-WS) is for the windscreen only. It does't show the parts for the installation of the holder.
Does anyone know a part number or part for the wind screen holder. When I pop off the plugs for the holder, it was just a hole. Is there an insert that goes there to snuggly hold the wind screen in? Its for the IS250c 2010.
