OK, what size is that bolt that goes to the top of the rail that the alternator top bolt bolts to (if that makes any sense, LOL)

Somehow, I lost mine.

12 mm hex M10 x 1.25 mm
from memory; I will need to be at work on Monday to confirm this.

Maybe I should clarify....

Not sure how I lost mine. :/

That one is not a bolt, but rather a threaded stud into the top of the block that the arm slides onto. Then a 10mm x 1.25 nut holds the arm in place.
