Instrument Panel

Are you trying to remove the complete dash, or just the instrument cluster? And yes, there's always one more screw hidden somewhere that's almost impossible to find and certainly impossible to see! I'm not familiar with the 68 Cuda instrument cluster, but could there be a screw somewhere under the edge of your dash pad? I sold my 68 Cuda in about 79, and oldtimers disease has set in since then. :)
