Astra mk3 chassis rotating jig

[GSIKING]

Does anyone know where the centre of gravity is on a mk3 Astra gsi shell?
I'm attempting to build a turret jig so I can flip the Astra over to work on the underside, I'm not sure how to work this out right so thought I'd see if anyone has this info as it would help me out a lot 😁

Rc on here is the only person I know with one for a mk3 astra. It'd be worthwhile looking at his owners diary
