isnt therre a nut at the base of the clutch? should be right there next to the bolts for the fan. you will need one of the clutch fan removal kits. rent one from autozone if you dont have one. if you have access to air and an impact hammer, put a chisel bit on the end, and use it to break looke the nut. if you dont have experience doining this, might be better off with the proper tools.
