Hot Rods Cragar S/S Lug nut question

I have a set of original Cragar direct drilled 4-3/4 bolt pattern I want to use on my car. The front rotors have the 7/16" stud size and that should not be an issue. The rear studs are 1/2" in aftermarket moser axles. When they direct drill the wheels and use the chevy bolt pattern are the wheel holes different sizes for chevy and ford lug nuts and just the thread size different, or will ford shank lug nuts fit these wheels on the rear without doing anything? Thanks

Thanks, I bookmarked that if I need it.

 

Most Mag style lug nuts have the same outside diameter on the shanks,,,just thread size is different.
