had to take down the ceiling panel to do some leak repairs...after drilling out all the rivets, I found that the moldings on either side (that run front to back along the edges of the panel) are riveted to the wall panels behind the ceiling panel itself...so there's no way to drill them out. I had to slip a putty knife between the molding and the wall panels, and snap the shafts off by tapping with a hammer. ok..no problem. Now, how do I put it back? should I just rivet the molding strips back the way they were, and hope that the ceiling panel can bend in a "U" shape enough to get the edges to slip into the molding piece? don't want to crease it.
