8-3/4 clutch type Dana power lock

yes ,, the above pic shows the correct stack for the factory stock clutch pack disc's showing 2 dished plates --giving an average preload of 200 ft/lbs in a stock factory power lock.---- replacement clutch pack Mopar Performance P4529484 has the identical number and shaped disc's giving an average 200 ft/lbs rotating torque in a stock factory power lock.

the new aftermarket powerlock unit i purchased-- --has the same number of plates and discs but replaces the second from right dished disc with a another flat disc and a thicker tabbed end plate giving an average of 90 ft/lbs rotating torque.---- the case halves are also machined an average of .020 - .030 deeper than the factory cases.

this is probably why DR Diff shims his units to bring up the rotating torque so the unit operates correctly -- but what is the number he strives for., so i guess a phone call is next.
( i know the built in ramps contribute to the loading of the side gears as well.)

just like to know what the minimum rotating torque should be for proper operation of the aftermarket power lock units being sold
