Re: Driveshaft Balance ( nuts and bolts )

    Trusty CarDisc to the rescue!
  Below is the bulletin, minus Fig 1
.
  Technical Bulletin # 89.01
  Group "15"
  May 1, 1989
 All GTV-6 and Milano Vehicles

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.
