Headlinder dropped, along edge

This is a view from front to back along the inside edge with the headliner dropped. You can see the side curtain air bag rolled up, and the mounts for the passenger visor (black clips in front) and the passenger roof handles (green clips). Further back you can see the cross beam that's 45" back from the windshield glass that limited how far back the rear rail could go. The mounts hang from a rail that's about 1/2" (just big enough for fingers to reach in) below the roof. When I dropped the nuts that separated from their carriers, one ended up in the "basin" by the clips for the passenger visor. the other ended up trapped between the roof and a beam that runs above the basin (not visible without a scope). I had to use the video scope to find and recover it.
