Ok, so how are all 6 "mini-supports" arranged in the roof?
2 long ones going front to back between the major ribs for panel number 2(from the front). That would give you all four buttons and the support for the 2nd headliner piece.
Where are the next 2 long ones located? And finally, where are the short ones located. Do they support the interior light, perhaps?

(Apologies for my re-numbering the panels from the front, in conflict from Tim's numbering from the rear. The installation would start at the rear due to the manner in which the bows are laid out. But if you've been following the discussion so far, it should still be clear as to what is being called out as far as ceiling panel numbers.)
