what size wheel studs on a 87 GN?

[Jeff Peoples]

While attempting to test fit some new wheels, I discovered my 7/16" lug nuts won't go on. Then I notice the "M" on the stud and "metric" on the stock lug. Duh.
So, what size lugs do I need to order?

Not sure the part # but i went to Oreilly Auto parts and found some that where 1/2" longer for $1.30 a peice.
