    With the SouthBend flywheel we need to torque the flywheel bolts at 3/4 of the factory spec (90Nm instead of 120, or like 66lb*ft instead of 90) because the SB flywheel is thicker and the bolts will catch fewer threads into the crank.
    Does anyone know of any flywheel bolts that have the same spec (material, thread) but at 2-3-5mm longer?

    When I did my SB clutch, I did OEM, and they were fine for about 60k miles.

    And after 60k they were not OK any more or that's when you had to work on the clutch again for different reasons?

    My throwout bearing exploded. Went oem all the things. Still were fine, but clutch itself was worn. Bolts were good to go.
