Since I have both sitting here in my garage, I thought I'd post up photos to compare the small and large 4 bolt Starion diffs.

is the big diff the smooth diff hat ?

Yep. The housing is slightly larger to accomodate the larger diameter ring gear. The torque tube is therefore shorter so that both diffs are interchangeable.

So the centre's are interchangable?

No, I don't believe so.

I haven't actually tried, but I believe the small one has a 180mm ring gear and the big one is 200mm.

The drive shafts are interchangeable, but the centres are not.

In Aus yes. Found in widebodies and other narrowbodies overseas too.
