Flywheel housing alignment is critical with multidisc heavy truck clutches powering 3 shaft transmissions. Not for chatter but to insure a free running mainshaft. It can be used with a model a to check for block/flywheel housing alignment but that deviation, if there is any is slight.

One area that can cause chatter is based on design. the clutch pedal cross shaft is attached to the transmission housing. In a car with loose or worn engine mounts when you 'load' the engine engaging the clutch the cross shaft moves as the engine takes load, creating a chain reaction against the pressure your putting on the clutch pedal. Engine mounts are key in minimizing this, often using after market float a motor rear mounts and the stock A front mount causes this effect.

Ford battled chatter for years, with the V8's they used an 'anti chatter' rod, a stiffener from the bellhousing to the frame..in reality an engineering bandaid..
