This is a front valance for a 633CSi. I should know because I just replaced one this past summer. I have never seen one of these on a 635. I have seen more of the 635 valances on 633s. That's not to say that you couldn't put one on a 635. I know somebody here needs this. Anybody know if this will fit on an '87? Check the guys other auctions, he's got some more 6er parts.
