Hi all Just want to say firstly my new BM is the finest car I have ever owned, I am I need of some advice please, today I replaced my stock wiperblades with some new Bosch, which I was advised were better and harder wearing, anyhoo after the guy fits them he tells me I cannot have my wiper blade covers back on as the Bosch blades are wider so I have had to leave them off, can anyone tell me if I am able to buy some new covers that take account of the Bosch blades and will fit.
