So the "Gen" and associated bezels can be removed from the front, but not turn signals?
Removing the instrument cluster is a difficult task. It is normally done
when the dash is being restored with a new pad. The dash pad must be
removed. Removal of the steering column will accommodate the removal of the
instrument cluster. Once the pad is removed go under the dash and
disconnect the the speedometer, tachometer, all instrument and electrical
connections including bulbs every thing must be disconnected from the
cluster. You will find the cluster is secured to the metal dash with studs,
clips and nuts once they are removed the cluster can be removed. The rear
portion is secured to the front portion with screws which must be removed to
separate the front portion revealing the turn signal. oil and generator
jewels.
It is possible, but not recommended, to remove the back portion of the
cluster from the front cluster with out removing the pad and cluster, but
you would need to be very patient, flexible and able to spend a lot of time
under the dash.
