Hi, just cleaning out the garage and found more parts i forgot i had. Since the z has been sold, everything is for sale. A good master cylinder was pulled from my 1991 parts car, $50 shipped, obo. I also have a complete set of rotor air guides that clamp to the tension rods, off a 1993 TT. They include all of the attaching clamps and hardware needed to install. This is a great upgrade for the earlier model z's as nissan didnt put them on until 93 i believe. Email for pics. Im thinking like $70 shipped for the rotor air guide kit sounds fair. The how-to is in the tech, but i included a link for anyone unfamiliar with this upgrade.
