To one of the AOM mounts we ordered from 3D Hubs, I added two tapped #6 holes to the following two locations, assuming the center of the mount is the origin: (+/- 0.875, 0.25). The y coordinate is not zero because there are existing holes at (+/- 0.75, 0) which would interfere.

The Gooch & Housego 3080-125 AOM fits very well onto these holes and it mounted in B102.
