Removal Procedure
1984-1989 Corvette Instrument Cluster
Step #1. Lower the steering wheel to the lowest position. Remove the tilt lever by turning counter clockwise.
Step #2. Cover the top of the steering column, next to the IP, with some strips of 2-inch masking tape across the dash panel below the cluster bezel to protect the dash plastic.
Step #3. Remove the head light switch knob by pushing a small screwdriver rearward in the knob's slot. The shaft will stay in the head light switch.
Step #4. Remove the Phillips screws holding the radio control dash bezel and set the bezel to the side.
Step #5. Remove the three Phillips screws holding the cluster bezel to the left outer IP.
Step #6. Remove the Phillips screws holding the cluster bezel to the IP and set the bezel to the side.
Step #7. Remove the three Phillips screws holding the IP carrier to the IP pad. These screws are pointed upward in front of the top cluster's edge.
Step #8. Remove the two vertical Phillips screws holding the center IP to the IP Pad.
Step #9. Place a 1 1/2 inch block between the IP carrier and the IP pad in the center IP above the radio. This releases any pressure on the cluster for easier cluster removal.
Step #10. Remove the four 7mm headed screws holding the cluster to the IP carrier--two above the steering column and one on each top cluster corner.
