Totally different in all ways,as are most all flywheels.
The stick flywheel is a big lump of iron.The rear counterweight is cast into the unit,so the flywheels from various years cannot be mixed up or your engine will be out of balance.There was also a clutch size change made in 83.
The Auto flywheel,like most AT cars....is not much of a flywheel at all.Its just a thin steel plate that the torque convertor bolts up to.The convertor and its fluid constitute most of the "flywheel" mass on an auto equipped engine.On a rotary,the rear counterweight is bolted to the Eshaft first,then the flex plate and convertor bolt on afterwards.
For lightweight, aftermarket stick shift flywheels,you use the AT rear counterweight that is correct for your year engine,then bolt the flywheel and clutch up.
