Replace the french lock on your 1963 - 1982 C2 or C3 Corvette with better technology WedgeLock Washers for half-shaft attachment. Unlike the old french lock that is easily destroyed and difficult to use, these new WedgeLock washers can be used just like a standard lock washer and they are re-usable. They are highly resistant to vibration and secure the half shaft flange bolts tightly by increasing force on the bolt head, and ultimately the threads, if they begin to loosen. This happens because of the wedges between the two halves of the washer. Make your Corvette more reliable and easier to work on with WedgeLock Washers from SpeedDirect.
