Hotchkis hood pin measurements needed

He measured from hole center, (north/south & east/west) to hole center using dial calipers. I can't get anymore info today, he's gone for the weekend.

Thanks for getting the info, i think he just measure in a square.

Mine are 1-1/2” measured like this on all sides
