i have a 91 integra ls and i took my entire cluster out one year ago to change the lightbulbs. i ended up breaking my speedo, but thats another story all together. if you wanna know how to take off the buttons, you may do this trick i used. i popped the actual buttons themselves out of their holes. they should pop out towards you. then you squeeze the plastic connectors to get them off. if that doesn't work, try using a small flat head screwdriver to pry them off. then the rest is all easy.
