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

For illustration purposes, here are two Cragar G/Ts (my favorite wheel). Not identical, but very similar to the S/S. On the old originals, the center casting may have been virtually identical.

The first is fifty years old, with no machined recess for lug nuts. The only thing you see is rash from the washer on the shank type lug nut.

The second is from a brand new Chinese Cragar G/T, made to use 60* cone type lug nuts. The machined chamfer is quite evident.
