Just did the single wiper from KE Laser on mine. Bit of rigging around, but it works well now. It is the rear wiper motor from the Laser as was just mentioned, but MD I put mine in the centre hole because I have the battery isolator emergency puller coming out of the drivers side one. Took a bit to adjust, but the arc goes from the edge of screen in front of driver to about half way in front of passenger side. If you are at QR on Sunday I'll show you my setup. Rob
