When the one on my '75 went out, the first symptom was a grinding,
scraping noise with the clutch depressed.  Then I got the stuff shifter
and grinding.  Eventually it seized completely and I was unable to
disengage.

I had clutch chatter, too, but it continued after the replacement so it
was unrelated.  On that van I'm pretty sure it was bad motor/tranny
mounts.  With a cable-operated clutch, this can cause a feedback loop
because when the tranny moves, you're effectively changing the length of
the cable!
