Awhile back I was taking a trip and while loading a dolly it pushed into the headliner and broke the clips that attach the two sections. The larger front piece is still attached and slides as expected but the rear section is now stuck in the back side of the assembly. I can get it out but what I am having trouble finding is the clip that attaches the two sections. Any insight on this? Also in order to replace that clip will I need to pull the headliner and remove the whole assembly or can I get away with removing the glass to access that space?

My apologies if this has been posted but I did some searching and couldn't find anyone talking about this problem.
