Alternator pivot bolt nut size?

[Z Prime]

Hey guys! I started my Z up the other day and one of the belts started squealing so I started to investigate. The nut is missing from the pivot bolt of the alternator, so does anyone know the size of the nut?

pivot nut? i know the big bolt on the top and then the tensioner underneath the alternator. which is it?

It Is The Big Bolt On The TOP That Is Missing The Nut That Goes On The Back.

If you're talking about the really big bolt that goes through both top holes on the alternator, then it doesn't get an actual nut. It threads into one of the brackets sticking off the block.

Or do you mean the tensioner bolt nut that holds the tensioner tight to the alternator?

It is the top big bolt that I am talking about. It got loose and so I got under the car and pushed the bolt all the way through both holes of the alternator and it didnt thread into anything so that is why im looking for the nut size req.Id rather not take the thing back out but i will if i have to. I was just checking here before i had to take it back out.
