Cragar SS Lug Nuts for my '66 Barracuda

toolmanmike said
It looks like the shank diameter is .592 where standard Cragar nuts sold are listed as .680. Special ones for the early A. It sucks they are on back order (like many items now days) but you will need the correct ones. You could start a wanted ad here on FABO and maybe someone has a used set to get you by but If you have new wheels you will want new nuts I would say.

I looked at the wheels and the mounting surface looks flat. There seems to be 2 washer options and one is tapered but doesn't look like I would need those. Correct?
