GT headliner

[NICKLEST@uwplatt.edu]

I recently purchased a 1967 MGB GT, and the headliner is sagging badly.  I was
going to re glue the material to the fiber board in the roof but it turns
out that the PO had glued the headliner directly to a piece of foam and then
the foam directly to the bottom of the roof panel.  My question is (since I
don't have another GT to look at) is that the way it is supposed to be?  Or am
I missing some sort of panel up there?

thanks in advance,
thanks,
67 MGB-GT
