Hey everyone, I pester alot of you on here, and I try to help when I can, but I have another curiosity.I just went and looked a 1981 320i, the only thing that I could see being wrong with it is I think that the master cylinder for the clutch died, because you cannot get it to disengage, and it loses fluid very quickly, I was looking at buying it from the guy, he wants 400 for it but I really cant offer more than 300 atm, is it possible for me to take the master from me 1976 316 and put it in the 320 and it work?I figure I could becaus they are both E21, but im really good at being wrong

yes, they both use the same clutch master cyl, part # 21521150782

thanks jester
