Hey kobes , i rang up a well known auto store last week to purchase a brake master cylinder for a 1970 240z , they tell me it is no longer available, and that later 240 and 260 are different, i thought bit odd, so i checked a later one against the 1970 model one and sure enough they are different, i still havnt obtained one yet, would you mind checking up on that for me , thanks ,Dazzed
