I have exactly the same problem, with an original alfa (=sachs) clutch. I
also asked the digest, got no reactions. One possible cause that I could
think of is play in the pilot bearing between rear half of driveshaft and
clutch shaft, or a damaged clutch shaft spider (that the giubo bolts onto).
I managed to reduce the vibration significantly by balancing the driveshaft
with two worm-drive hose clamps, but this is not totally satisfactory. 

Anybody have any suggestions?
