Hi Hope someone can help me . I have a Lupo minus the Rear wiper { Just a nasty grommet } The wiring and washer tube are there . I got a reconditioned rear wiper motor and chap went to fit it but said there should be a collar/grommet that fits through the hole in the rear windscreen then over the motor shaft to stop water getting in . Question > Does anyone know where I can get one of these and more importantly being that Im a female would be good to go in to shop or breakers knowing what the Part is called .
