Paul,
Sure seems I'll be going in there. Really hoping it's not the input shaft, but surely that would make noise (as you mention) when clutch is out as well?
I'm considering to get a clutch kit from ecklers or something. They're about $400 including pressure plate, pilot-, and throwout bearing.
I kinda want a new DM flywheel as well, but then we're in a different league cost-wise. Not that the price is a problem, but annoying if the old FW is still good. Can you tell if it's busted with the tranny/clutch removed?

Anything else one might need in there? clutch fork pivot ball?

From the ZF.Doc

I replayed the video about twenty times. It sounds like the pilot bushing is
compromised.
Install GM fluted pilot bushing (GM P/N 10125896). WARNING: Applying grease
in a pilot bushing will cause the pilot bushing to fail within the first one
percent of its normal life expectancy. Although very dry looking straight
out of the bag, the oil-lite type pilot bushing is infused with enough oil
to lubricated the input shaft pilot tip for the entire service life of the
clutch. Why not just install a pilot roller bearing instead? When a pilot
roller bearing fails, the input shaft pilot tip will be compromised
requiring removal of the input shaft for pilot tip repair or replacement of
the input shaft.
