84  Van.  Is there a simple way to stop the silly clock?  When camped in  a
quiet place, my analog clock audibly "thunks" off each second, even  though
it is only correct twice per day, mostly.

yea.. scrap that old cluster and install the later one with the
tach/digital clock like most everyone else has done.   your behind the  times, don!.
  want to keep your old speedometer with  odometer?  just unscrew it and
screw it into the newer speedo  cluster.  you keep your existing mileage and
you have the newer cluster w/  tach/and quiet digital clock..
