I have the p/w and w/p pulleys removed. In trying to remove the cap screw from the front of the fan clutch I had a narrow piece of metal to catch on two of the four bolt heads that hold the fan pulley on the shaft. Well as Murphy's law goes the metal slipped on the bolt heads and before I could stop myself the metal caught two fins on the fan clutch an broke them off. (OH BOY more parts to buy!)

Any recommendations on how to hold thus shaft in place while I attempt to loosen the screw?
