Yup, 1 hour job, remove center bezel, remove bezel from around driver side dash, unbolt old cluster, gently put new cluster in it's place. The clusters use self docking plugs but be gentle when putting them in, don't want to bend any pins in there.. I used a gauge cluster out of a 97TJ in my 98. You can probably use the same years 97,98,99 and maybe 00, not sure about the 00, some stuff could have changed, I'd hit the dealer and see if the part numbers are the same for those years...
Oh, disconnect your battery and let it sit for a while, don't want to chance popping an air bag, rare but the factory manual directs 'disconnect battery and allow to drain'...
