It just amazes me that some numbnut engineer (of my discipline, but yes pajorative) comes up with a nut for the No. 10 (maybe 8) stud that is neither 5/16 nor 3/8. And, I recall a time when I was out of town in my mopar diesel truck with a bad starter. Under the truck I go, after finding one at auto parts. In the lot, at nite, and yes, the Dodge, now Ram, had a 12 point metric bolt that held it in the truck. BUT, I will say that I did not have to dig out an 11/32 wrench for the solenoid wire. What were they thinking. Having worked govt, I do not know whether the Snap On set includes this size, but am doubtful, since only the ignition wrench sets seem to. Aaargh.
