cheers, kinda feel stupid i didnt think about it before... :S

Recently the lights behind the fuel/temp gauge in my corolla have blown and i was looking to replace them myself. I removed numerous plastic panels including under the steering wheel, the center dash/above the steering wheel, the black panel around the instruments then the screws for the cluster and even the radio but i still couldnt get in to undo teh speedo. Just wondering if anyone could give some help on how its done?
