Cragar is the only company that makes nuts for these wheels, the Gorilla nuts are for unilug as shown by the washer and diameter. Like I said before, I never had problems with them and the only thing may be the thickness of the washers. I have a few originals around the shop, I can take measurements tomorrow when I am out there. Just put Cragars on a 69 Dart last November with no issues. This is where I got them last year...
