I just had mine apart and if yours is like mine it is pretty simple. I have an 01 GC.
-put the steering wheel in the lowest position
-pop out the center trim piece below the speedometer.
-this will expose two black philips screws, remove them
-remove two upper black screws in the trim ring
-remove the trim ring by carefully angling turning it as it comes out
-remove the four black screws on speedo/gauge assembly (two on either side of it)
-roll the assembly towards you as you pull it out. There will be several gray tabs on the back of the assembly which are the gauge lights. A quarter turn with a needle nose plier should get them out easily.
-Do the process in reverse to put the gauge assembly back together.
