Competition Parts from Rallye Enterprises, Ltd.
bars have a diameter of 22.2 mm (7/8 inch) and are
about .8mm (about 3/10 of an inch) smaller than the
original Datsun Competition 23mm bar. As with the
originals; these are designed to be easily installed
using the stock mounts. You
will also need to order the larger round bushings
unless you have some.
