well you need a good set of circlip pliers and the clutch compressor tool to do your secondary spring, and you have two springs?.. is one bigger than the other? because there is one spring in your secondary and one in the primary... the one in the primary is smaller, for that one you need no special tools, just unbold the 6 bolts on the cover, remove it along with the old spring, then re-install with the new one, just make sure to pull the cover back in over the spring pressure evenly (circular pattern) or a second set of hands to just push on the cover helps too.. good luck
