The lead hammer furnished with the car is for one-time emergency roadside use; you need a "Muther-Thumper" REAL lead hammer. Google "Muther-Thumper" and you'll get hits on where to order one - all the Cobra guys (and experienced Corvette KO wheel guys) use them. Photo below of the "Muther-Thumper" on the left and the hopeless one-time-use hammer on the right.
Virginia Vettes and Long Island Corvette Supply both carry a neat rubber suction cup tool to remove the decorative emblem/cap from the spinner without tool damage.
