Height of Bosh Gearbox Mount?

I need to know the exact (within .002) height from the mounting plane of the plastic drill gearbox mounts to the axis of the output shaft of the gearbox. The Cybersonics have it modeled really well but I can’t be too sure it is perfect. Does anyone know this dimension?

Does anyone have this info? I would also like to know.
