So, the nut that holds the sc tensioner onto the stud going through the cast iron coil pack bracket. Its special. A normal nut that threads on is a 15 mm, but you cant get a socket bigger than a 13 in the tensioner hole.. So its some kind of special nut with the same thread and pitch but a smaller head. Any idea where to get one? I even looked around at my local ace/lowes/home depot and looked through mcmaster carr and I cant seem to find ones with a smaller head. its M12 I believe. If i cant find one i might just grind the crap out of one to make it smaller lol.
