The stack height is critical due to the reverse torque limiter and with out having a mock up crank case it can be a little tricky getting it correct.
I'm pretty sure the friction plates (as are the ones from the C10's I've done) are extremely consistent in their thickness'
with that said, unless you find severely warped steel plates (which would have been very evident by now), simply disassembling,
noting the plate locations in the stack (the steel "off size one's locations"), while soaking the frictions in an oil bath for an overnight pre soak, and reassemble all per FSM, will safely refresh the system to it's as delivered state, without requiring the tedious messing around explained in setting stack height. I cannot think there would be any issue whatsoever, when using OEM frictions only... even if you "buff" the steels lightly with a Scotchbrite' or even 400 grit wet-or-dry paper, I do stress lightly tho...
my clutch has 'groaned' when abused, since day one... It hasn't effected its job tho, I liken it to it is talking to me, saying
"ohhh nooooo, not AGAIN...."
