Thanks for the suggestion, Doug. I normally mount safe/vault locks on 1/4-inch aluminum plates and drill/tap appropriately on a milling machine. Having an "official" template/drawing makes this much easier. With the Manifoil I also have the round shim to make measurements from. An unusual feature (compared to S&G/Mosler/Diebold) is that the spindle bushing protrudes from the case, and that there is also a round "button" which must be there to ensure orientation (though the uneven mounting holes should assure that) and possibly block forceful rotation of the case.
