HELP - Cragar SS Lug Nut Washers Keep Crushing - Need Alternatives!

Dave, do/did yours loosen up?
As mater of fact the fronts did Steve. The Cragars were on it when I traded for it. The car saw many weekends at Oswego and Union Grove before I ended up with it. It took a lot of abuse. I was driving this car almost every day except in winter way back. It was a nuisance thing. I knew about it and just tightened them up regularly.
The rear axles were drilled to 4-1/2" and those 10 X 15s were "unilug" which never loosened up. The old Cragar single pattern lug wheels that never had a problem are still laying in the shed.
