    Napaonline sez that the clutch disc on a CJ with an :hurrican: and a T90 should be 8.5", yet Brian gave me one off of Wimpys old engine today and it measure 9.25".

    What gives? :? Was there some kinda "heavy duty clutch" option that they're not acknowledging or something?

    9.25 was an option.

    Some flywheels are not drilled for a 9.25 disk. Before switching from one to the other, bear in mind that the clutch control lever and tube is different for each application

    I'm not sure exactly what the differences were, but I know that the lever and tube for the 4 speed is different in both length, angle, and size of the rod bosses (tabs).

    IIRC, one was called an Auburn, the other was a Rockford. Can't remember where I got that; wasn't in the Owner's manual.
