The instrument cluster is all one piece, I believe. You can remove the panel it is mounted in, but taking the actual cluster containing speedo, gas gauge, temp and charge gauges, odometer and turn signals is another matter. I'm sure it can be taken apart, but you might have to pry out or drill out some plastic tabs. You might look for the instrument cluster in a junk yard or ebay to have one to practice on.
