Need to know proper stock lug nut wrench size - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a customer in Spain that needs a lug wrench for his K5. I already have a package ready for him with some other parts and would like to include the lug wrench to save him on paying for shipping on two different packages. I got a lug wrench from a c10. Is it the correct size? I would assume it is but have searched and can't get a definitive answer. I don't want to lose my shipping cost on it if it is wrong so I appreciate any information you guys can help me out with.

For squarebody pickup, Blazer and Suburban:

K10 4x4 has six lugs; studs are 7/16 and you use a 3/4" socket to remove the lug nuts.

C10 2wd has five lugs; studs are 1/2" and you use a 13/16" socket to remove the lug nuts.

Keith, Thanks for the response. Somehow I didn't get the notification until now. I got it sorted.
