77 gillig ceiling panel removal?

[butteryak]

Hey I'm wondering about my 77 Gillig, if anyone has any experience on removing the inner ceiling panels, I see no visible screws or rivets, there is just a seem, before I start tearing into it, I"m wondering if anyone knows how these panels are attached, There is no externally visible method of how these things are attached, I'm getting ready to take them out, curious if anyone out there knows about this particular model/year, and what I may find once I start taking them apart, or how to go about doing it.

Thanks much, looking forward to my adventure

here are some pics.

What's behind the channels on the side? Could be hidden behind them...
