John, I have confidence in you, no doubt. Let's study the wave-plate... just above the head side of the exhaust pipe. That puppy has to be flat when all is assembled. Right now statically, it's curved. Trick #1. Trick #2 is 1/8th out from a seated ramp position. Trick #3 is to hand palm the stacked steels and visually see them lay without a gap if you spun it 360 looking for a warp. Last is the hammering of the big clutch outer channels, meaning, no deep grooves, but more like a shadow print and your fingernail can run across the channels without catching a nail sunk in a groove. So that's both clutch center channels as the big clutch outer grooves stopping the plates from floating but stuck in those grooves.
You're to doctor now. Every part is an inspection for cracks, normal wear, strange etchings, etc. Having a Clean operating room wise, you are the doctor!
