Well again thanks for the part #,s But to let you all know that I have boughten two Crossfires an 04 coupe and the 05 SRT6 and they both came stock from Germany with deflectors on both wiper arms, and this is why I know that they are on both sides, I have had this trouble before with the 04 and the 05 on wiper arm deflectors, now the dealer said that the 0509905AB was superceaded by # 05189813AA, which does not come with the deflector. I don't want to say you guys are wrong, but the two xfires I own did come with them originally, I will check on the Benz part # so maybe I am the unlucky one who got what we all should of gotten when we bought our xfires ??????
