Cragar S/S Wheel Locks

I have searched high and low for some Cragar S/S wheel locks and am hitting dead end after dead end. S/S's have a smaller whole than most mags and have special lugs. Since these are such a popular wheel with older mopars I was wondering if anyone has found a supplier out there? The specs for a 1966 Barracuda with Cragars are 7/16-20 (All right handed since I replaced the wheel studs). Thanks in advance,

Bill
