Welcome to the fun o f removing that cluster. Is this a 67? It looks earlier to me, like 66.
if it is 66 you will first have to remove the radio, heater panel, which means all the heater control knobs and radio knobs come off. Also the ash tray. Removing that panel gains you access to the right 2 screws which hold the cluster to the dash.
