From the CarDisc (everybody should have one!):

Technical bulletin 89.01. dated May 1, 1989

"During assembly of the GTV-6 and Milano models of Alfa Romeo, the
factory precision balances the driveshaft on the car.  The balance of
the driveshaft is adjusted by using different thickness nuts and/or two
nuts on one bolt.  (See Fig. 1)"

"All hardware and driveshaft components MUST be refitted exactly as the
factory assembled them."

"Whenever removing or disconnecting the driveshaft from the vehicle mark
the position of ALL mounting hardware and driveshaft components so that
they can be returned to their original position to preserve driveshaft
balance."

So there it is - all you have to do is look!

I've forwarded copies of the TSB to John off-line.  If others are
interested, lemme know, however it's pretty much the text I copied plus
a pic of the drive shaft and hardware, nothing special.

More comments on the CarDisc - I've got a whole bunch of them, all
converted to HTML.  Wonderful - I've got thousands of pages of material
from the 50's through the 90's, all loaded on my laptop computer.  How
else could I have gotten it all onto this plane..
