I’ve got a 3600 with an open driveshaft… all shackles/bushings are new and I have long, anti-wrap spring perches that I would expect would help a little with spring wind-up.

I just discovered something else- see pic. I put the flywheel on the bench, centered the disc on it, then carefully torqued down the cover plate. The clutch fingers/levers are on not all even- I centered the throw out bearing on it and took this picture-
