First, pull the steering wheel off and remove the lower cover
from under the cluster and remove the lower cover bracket. If it is
an automatic, disconnect the shift indicator wire by unhooking it
from the right side of the steering column. Reach behind the
cluster and unscrew the speedometer cable from the speedo. You
should also be able to pull out all the wire connectors from the
gauges and the light bulb sockets from the back of the cluster, or
you could do it later when you are able to pull the cluster out
enough to reach behind it.
Then you have 2 choices: 1)You can unscrew the 3 screws in the
turn signal housing and pull the turn signal housing up. This
reveals the locking ring the screws were screwed to. So rotate and
release the locking ring from the notches in the top of the column
tube. Remove the shifter lever and pull the shifter housing up so
that it clears the cluster housing. Watch your turn signal and horn
wires, since you may have to loosen them to have some slack when
you pull up on the turn signal housing.
Or 2) You could loosen the clamp on the firewall from the
steering column, and the clamp that holds the column to the bottom
of the dash and slide the entire column up enough to clear the
bottom of the cluster housing.
Then remove the 4 screws holding the cluster housing to the
dash, 2 on top and 2 under each side. There should be 2 nuts to
remove from behind the cluster on the bottom. They would be on the
2 long threaded studs that are visible when looking up underneath
the cluster.
Pull the cluster away from the dash tilting the top towards you.
Pull it out enough to reach behind it, if you didn't pull all the
wire plugs and sockets from the back of the cluster before, you can
do that now. Otherwise lift the cluster out of the dash.
