1981 300SD: alternator tensioner bolt size?

So I'm replacing my father's 1981 300SD's alternator, getting towards finishing, when he comes over and says, "Hope that tensioner bolt don't break..." Well, you know what then happens, right. The bolt was originally slightly twisted (guess the PO didn't know to loosen the mounting bolts first) and I can't get that special nut off the broken end of the threaded rod/bolt. I tried figuring out what the threaded rod/bolt was but I can't get any nuts of any size or pitch onto it. So, anyone know what the size(and pitch) of that threaded rod is... the one that has that special nut on it that you use to loosen/tighten the alternator belt.... you know, the one that's welded onto the side of the head of the mounting bolt? Thanks.

Taking a guess it's an M8X1.25, can you take part of it with you to a hardware store and double-check, or am I missing something. MAKE SURE it's not a left hand thread, little fuzzy on that tensioner right now, but I kinda know what you mean.

PS You can take the larger bolt off that holds the "eye" side of that special bolt then I think you'll have the whole threaded rod in your hand.

Thanks for replying. Well, I managed to get the broken side out of that nut and from what I can tell it appears to be a metric 6 size, standard 1.0 pitch. There was a slight bend in the threaded rod and I think that may have messed up the threads in the nut slightly. I can always retap the threads on the nut, but I'm going to try getting the m6 in all the way today and see what happens.
