7/16 or 1/2 inch?

 

I'm pretty sure those are 7/16", two each right and left hand thread.
They are definitely old, as McGard moved out of Buffalo to Orchard Park decades ago.
If Jim passes on them, I would like them. I wouldn't use them, but keep them as a cool old local product.
Jim, I'm sending a PM to get them if you don't want them.

 

They're yours.
Have no need for 7/16 inch ones.

 

Thanks Jim.
