You have to unplug all the switches in the rocker switch panel and then pry it out first by getting a wide, flat blade screwdriver behind it. Move around to various positions and try to get it out evenly. After it is out its easier to take out the cluster. You'll also need to disconnect the speedometer cable from the cluster and disconnect the alternator gauge's 2 wires from the cluster as well. Removing the ash tray and cig lighter assembly will help in getting to the back of the cluster nad rocker panel.
It would be worth it to remove your seat as this will create a lot more room for you to get up under the dash. With buckets its easier than with the bench seat. While not absolutely necessary, I've removed everything with the bucket seat still in the car and moved all the way back but I still wind up standing on my head and twisted like a pretzel.
this is exactly what you need to do I have had my 69 dash apart 20 time its a petzel nuckle busting job , but i have it down to a science now .
The dash pads(around the switch panel ) swell over the years they are a very tight fit , just keep at it . it will come out , be gentle and dont rip the pad or distort and metal frame in the pad . Then the pad will look like crap and all bent .
