If the bass is laying on its front the weight of the neck will pull down the upper ribs unless the neck is supported. This will, of course, make a gab between the back and the upper ribs.

I would probably draw it down with clamps and let it set for a few days before I glued it. You will need to make sure that the neck projection height and alignment are correct before gluing.

Wayne,no neck pull as the neck is off and the top is perfectly in place with no tension at all ...

There are 3 possibilities
1. as you say , the back lost its shape
2. the ribs were cut down at some stage
3. the maker didn't mind 'springing the back'

I have attached pic with a torch shining in the gap to highlight the gap...
