roof supports

[Lumpy]

I got a 78 gp and tore the interior apart this weekend. I took the headliner down and it seems like the roof supports are hanging down. Are those supposed to be flush with the roof or welded to the roof. The roof isn't dented or anything so what would cause this to sag?

They're not welded to the roof. There's a rubber-like body sealer that is between the support and roof that glues them together somewhat and keeps them from make noise.
