flex plate
Considering the confusion about the flex plate and it's clamping and should you use a Porken pklamp or a Constatine clamp, the idea is to stop the drive shaft from movement relative to the clamp (the flex plate by design is what takes up the drive shaft's torque twist shrinkage and expansion during acceleration and off throttle. Some say because the torque developed during acceleration is larger than the torque reclaimed during off throttle that the flex plate slips. I'd say that energy in is energy out, it may not be applied at the same rate but it be will be applied, therefore the flex plate should return to the original position.
That all being said, my flex plate, when relieved of pressure did return to flat, but had a slight bow to it. To stop all this, why not set the clamp ( fly wheel pulled aft ) by backing off the allen bolt to slack, drill the housing and axle and drift in a split pin. It would seem to me the perfect solution, no movement at all. tom |

Tom, adding a pin to the clamp isnt a good idea as it will weaken it, and your not going to be able to drill into the driveshaft its hardened.
Best to check the clamp bolts and tighten them to 66ft/lbs Add a drop of blue loctite on the bolt thread you should not see much movement . Make sure to check the rear clamp bolt after removing the front clamp bolt. If either of the clamp bolts have shank damage then they should be replaced. Usually the rear clamp bolt is loose use the torque wrench set to 66ft/lbs to see . Also if the rear bolt has shank damage then the driveshaft needs to be moved forwards or backwards so the cutout is lined up
