My wiper blades (2005 4/4) have little black plastic caps at the ends. I have lost two, presumably when washing the car. I guess they are there to reduce the likelihood of scratching the screen should the blade flatten out, but they don't seem to be a very tight fit. Do they matter? Does anyone know where I can find replacements - I can't see them listed in the usual places (Rutters, Heart of England)?
