Shock Arm Retaining Bolt

[Philip Hubbard <phubbard@carroll.com>]

In putting the upper trunion bushes in the passenger's side today I found
that the shock lever arm retaining bolt is stripped...the inside of the
hole looks bad as well.  I tryed putting in another bolt but it wouldn't
take either so I imagine it is the threads of the hole.

Anyone know what size threads those are and can I use a tap to do it?
Looks like about a 5/16" x 24.  Am I close?

Thanks,  back out to put the other spring on and wheel the car into the
garage.
