Len, if Tracy's damper plate is used, it bolts to the flex plate, just inside of the ring gear. So for our purposes, the flex plate does deliver torque loads to the gear box.

Charlie

So, make a flywheel just big enough to pick up the bolt pattern of the damper plate and bolt it on over the stock flex plate. So the flex plate is not loaded at all except for starting the engine.

Or, buy a racing steel or aluminum flywheel and bolt the damper to that.
