www.vagparts.co.uk i bought my rear aero wiper from. was a pain in the ass the fit and needed to cut it a lot to get it too fit. it was too low and scraped on the window. needed to cut the arm and the cap that goes over the washer jet. but fits fine now!
and wipes MUCH better than a standard wiper! rear window can be soaking wet and it will totally dry it, literally squeaks its so dry
