Shift Knob Jam Nut 1/2"-20 3-Speed 1965-1967/4-Speed 1965-1969

With the addition of a new CJ Shift Knob, a jam nut is required for proper installation onto your shift handle. Without a jam nut it is almost impossible for the new shift knob to naturally tighten on the handle and to be properly aligned at the same time.

Features the correct 1/2"-20 thread pattern for your 65-67 3-speed or 65-69 4-speed Mustang.

*Sold individually.
*CJ Shift Knobs do not include a jam nut.

Please Note: Most early model original style shift knobs already use a jam nut, therefore you may reuse your existing jam nut for your new CJ Shift Knob.
