If the touchup before clearcoat was a good one, I wouldn't re-install it.  Manuals and Flyers are made well before final production and often have features different to production models (different colours, wording, plastics, etc).
I'm pretty sure centre posts were asked for by a few european distributors for whatever reason and that is why we occasionally come across them in games over here.  I have never seen a T2 in the flesh with a centre post and would leave it out for a more challenging game as it was originally designed (I would suspect, you could email Steve Ritchie for confirmation though, it would definately set the record straight)
