I think I might just be losing my mind. Took it out and played with it too much. Here is the

Pierre,
Along these same lines, it would be easy to make a set of Go-No go gages.
Take some bar stock, drill and tap two holes. Drill flanking holes that are
perpendicular to the tapped holes major axis. Modify these holes so they
work like a clamp. Then you can set the space between the half nuts.

In the kerf where you sawed the nut in half. If you tilt the two
halves to touch on one side, they should form a gap on the other side
that is consistent from bolt to bolt, assuming that the bolts are all
the same size. I think that you could estimate the difference between
PD of two bolts using the difference in the gap and a bit of
trigonometry.
