Cragar SS Lug Nuts for my '66 Barracuda

So the threads on my studs are 7/16-20 for certain. I'm going to HF for an inside mic to measure the wheel lug holes for sure and will let you guys know for sure. FWIW, I think the newer Cragars use different tooling than the vintage ones and so the sizes seem to be different. My '65 Dart studs with original Cragars are completely different size.
