Cragar Lug Nut Help

Lug nuts are perfect.
Washers not so much.
Too big, but we knew that.
The washers are concave, so I guess I would have to shave extra off one side as they will spread out as they're torqued.

I would order some of the McGard, but the lugs are a bit shorter, will try to find just washers.

Were the old school washers concave?
