Few thoughts/comments

Yes driveshaft turns at engine speed so should be balanced, u-joints in proper phase and straight--also with such a short shaft , u-joint angle is critical

We have a customer with original Shelby gt500 mustang that we built a stroked center oiler for--he used a centerforce(I am a long time friend/fan of Bill Hays) aluminum flywheel and is on his third one in a little over a year---starter ring gears aren't shrink fitted to the wheel but are fastened with 3 tabs around the outside--now they have gone to 6 tabs--these keep coming loose----

The sprung hub clutch discs have various numbers of hub springs and some are dampened with rubber slug inside the spring--this will kill off the chattering on engagement

Lots of chatter comes from hanging the trans by the input shaft during install bending the disc so that it doesn't made full disc contact upon engagement
same deal on having difficulty engaging gear at a standstill---clutch won't fully didengage because its bent

From my days of top fuel/funny car and pro stock racing I have a container (tank/artillery shell) full of matched springs grouped by pressure, adjustable stands, and a tool box full of weights, arms, etc---I'll try to get a pic of some of the stuff, altho it doesn't apply to this, it will maybe open some eyes as to what these things do to the clutch operation
