basically you pull the back cover off, on each gauge you see 2 tabs retaining it bend them so the gauge comes out on the center of the baord you stt a tab it locks the board in just press on it and gently pull around the board loose until the gauges on the other side comes off. but it's a dangerous job as you can easly mess up the gauges, I repair gauges and mod them on my spare time so it's easy for me to do, then the bulb pulls off to reinstall I usally put all the gauges clear housing and all in press the board in gently almost all the way in then pull the front off with a clean cloth push it in until the retaining clips are all the way out.
