I am reinstalling my alternator and I guess I mixed it up with another long bolt, since the thread isnt catching at all. I just decided to buy another bolt from the store to replace it, but before I do that, I need to know the width,length,thread. I would like to get the size soon before the store closes.

 

just get a bolt with a matching nut. just SWAG(Scientific Wild *** Guess) the size.

 

I guess I might have to...

 

i had to do that when i dropped my alt. bolt in the gravel. i just brought to alt to the parts store and just got a bolt to fit over, and a bolt to fit.
