As for what fits, 94-01/02 are the same sheet metal. As for the dash itself 94-97 are the same and 98-01/02 are the same. The entire vehicle harness and electronics changed in 98 and 99. You'll have better luck finding a decent 98+ dash core, but you better be good with electrical with a little fab skill if you want to go down that road. The door panels also changed in 98, not sure how they match up to the dash, though.
