Did you read the section in the 700/900 FAQ regarding the 940 instrument cluster?

940 Instrument Cluster Removal. [Query:] How do I remove the instrument cluster in my 940? [Responses: Abe Crombie and IanB] We got it out with a small screwdriver which will go through the slots in the side of the plastic bezel. You will feel a spring clip as you push into slot. Push the clip hard while pulling toward you with the shank of driver; the clips are attached to the dash and are also robust, not easy to damage. The surround is alloy and is held by the cluster screws. There are lugs cast into the sides of the surround onto which the clips lock. Do one side only, it should come out easily once you get one to let go. One clip each side, nothing else holds it in. After you get it out remove the cluster by taking out (4) Torx screws and it's out. If it's turbo you have a gauge hose to disconnect at a joint about 8 or 10 inches from gauge. The latter is easier to do with the kickpanel above brake removed. Before you replace the bezel, grease the spring clips and the lugs to make future removal easier. To replace the bezel simply push it in and the clips lock onto the lugs.
