Where to buy Cragar ss lug nuts

I know that the Cragar SS wheels don't have traditional lug nuts and was wondering if you guys have had any luck finding them in local auto parts stores. If so, which one? I just got a set of wheels that someone had on a late 60's dart so 10 of the lugs are left hand lug nuts. Since I'm putting them on a 74 dart I need to pick up 10 right hand lug nuts. I would just get them from summit, but I need to put the wheels on a car I'm picking up this weekend in order to make it road worthy.
