Lug nuts

I'd like to buy Ansen Sprint rims. And at the same time I'd like to buy appropriate lug nuts for it. It's clear that the seat is conical, 60 degrees. But what is the correct thread size?

These are offered at Summit Racing:

• 14mm x 1.50 RH
• 1/2-20 RH in.
• 12mm x 1.50 RH
• 7/16-20 RH in.
• 9/16-18 RH in.
• 12mm x 1.25 RH
• 14mm x 2.0 RH
• 12mm x 1.75 RH
• 9/16-18 LH in.
• 10mm x 1.25 RH

Could you please help me to choose the correct one?

Thanks, Tomi

   i see why that was a hard question for me ,it was to easy. yes definitely 1/2 possibly all as far as i know all 60s and 70s u.s. fords were 1/2 inch. you could have narrowed it down because there are no metric nuts or bolts on your car.guess you have starsky and hutch torino.like the aluminum slots always have.if your trying to be correct with the car i think it had wider wheels in back.always smart all 5 same size for driving car.   i would ask the company that makes the wheel for a suggested lug nut,but bieng conical sounds like they eliminated the issue that concerned me.but you should still ask them ,i dont think the correct lug nut will look like a steel wheel nut.  460  i like.
