thread on starter solenoid

["Donald H. Locker" <dhl@mrdog.msl.com>]

Hi, Folks.

And the rest of you, too.

Anyone know what thread was used on the starter solenoid power posts?
It is very nearly, but not quite, M8-1.0 or 5/16-24 UNF.  Is this one
of the magic British thread specs?  Anyone have nuts that fit or a
recommended replacement source?  (I have two and need two more.)

Thanks,
Donald.
