O-2A Moment Arm/C.G. for hard point/stores

[JMH]

Wondering if anyone has a layout/Diagram or some other reference for the moment arm of the hard points (or specific stores) for the O-2A. Or actually Wt/CG info in general for the aircraft... the dash-1 (T.O. 1L-2A-1) nor the weapons delivery manual (T.O. 1L-2A-34-1-1) don't seem to address it (however I might have missed it)... surprisingly they don't even list the empty weight of the acft.
