Lug Nut Size?

Anyone know for sure, the lug nut size and bolt pattern size for the 67/70 Chevy/GMC 6 lug wheels? Are they 1/2" or 7/16" lugs? Is 6X139.7 the right wheel pattern?

thanks........

Re: Lug Nut Size?

The reason I'm checking on this is that I am using rally wheels and late model caps that use the double thread lug nuts.
