alternator pulley nut size

[87lc2/wo2]

I am going to replace my stock alternator pulley with a billet aluminum pulley, but what's the stock pulley fastener's size?

Ask RJC Racing. They make an billet nut.

15/16" at least on mine anyway. Just tried it.

Billet nut is 7/8"

Mark,
Awesome. That's what I really needed to be sure before I put the new pulley on. I got that Impact socket for sure and my new cordless Ingersol Rand impact tool charged to take the factory nut off. I'be been waiting two long weeks to get the Turbo T running again. Again, Thank you.
