Use the main search engine, the fourth item over from the left in the string of tables under your name. I used "gauge removal" without the quotes and got a single page of items.
I am figuring you already have the front seat out, if not, that does make the job a little easier. It is still a pain in the butt and the back.
The gauges are held in place with a u-shaped keeper. This has a knurled nut holding it to the gauge. With that off (watch to be sure the brown ground wire is there for re-install) the tach and speedo cables are held in place with a screwed on holder. You also will need to pull out the holders for the bulbs.
Be careful on the center cluster. The temperature gauge is a closed unit, filled with gas, kind of touchy. If you knick it, repair time. Also the oil gauge is a direct connect to the engine. Sometimes you may have enough play to just move the whole unit forward without removal.
