What is blocking access to the problem screw on the right side?
Is the padded Instrument Panel blocking the screw?. I can't picture what the dash looks like on your car. Did you remove the lower trim panel underneath the steering column? Some times that has to come off to gain access to more hidden screws.
I don't think any part of the dashboard is glued together. My 89 Cav Z -
24 cluster had about 4 screws holding it in. The two side panels on my Z were held in by 3 oval shaped spring clips. All you had to do was pry a bit till you got two fingers behind the panel then pull straight out.
Can you post any photo's of your dash?
