I need a new master cylinder for my 78 280z 2+2. I want to get the whole complete unit new with caps and everything. I've searched the internet and haven't been able to find one. On ebay they had one for 70-7/77, and one for 79-81, but none for the 78. Will any of these other ones work in my car, and if not, where can I get one? THANKS

Motorsport Auto, Courtesy Nissan, Napa Autopart, your local Nissan Dealer, etc... There are plenty of options out there. One thing I noticed with my late model 78 was that few parts were 79Z parts.
