Alternator Pulley Nut Size

I need to find the size of the alternator pulley nut. My 93 5.0 lx is missing the nut on the alternator and short of a junk yard I don’t know where to find the nut at. I performed some searches and I could not find the size of this nut. Any and all help would be great!

If someone doesnt answer this before, when I wake up I will head out to the garage and check. I believe I had to buy like a 1 1/4 socket to get it off...but that was a few years ago
