Figures for WASP won't be far out if you don't get the Scout figures
MAUW 5500lb
F/A Cof G range 3.75'' fwd of datum to 5.5'' aft of datum
Lateral Cof G range 3'' port of datum to 5.75 stbd of datum
IIRC datum plate was on cabin floor just in front of the rear bulkhead, it's been a few years...
Hope it helps
