Hi all. I want to get some replacement wiper blades. I bought some from Halford but when I went to fit them they look cheap compared to the original wipers. The original wipers have a replaceable blade in the actual wiper unit rather than replacing the complete wiper itself. Does anyone know where I can get these as I have looked online and can't seem to find them. It's an 08 Accord EX GT I-DTEC. Thanks
