has anyone replaced this type of wiper blades before, im looking to swap my blades for some of the aero ones you can get that clip on to your original but all i keep finding on ebay are the type that fit the hooked wiper arms, mine are the early 03 silly clipped type, i only want to replace the blades with aero and dont fancy replacing the full arms too for the later aero type as they seem to go for mega bucks!
