This is a set of 2 (front and back) carburetor rebuild kits containing all of the OEM-style replacement components you will need to rebuild a set of 1972 Datsun 240Z round-top carburetors. These kits contain replacements for all of the parts that most commonly degrade in a Hitachi SU carburetor -- gaskets, o-rings, fuel-line, and a needle-and-seat assembly.
We also offer a complete set of video and text guides to removing, rebuilding, cleaning, and adjusting your carburetors. Specifically, you will want to checkout our guide to rebuilding and cleaning your SU carburetors.
