Hard top install kit - dropped bolt
 

Hi all
I got the left side done and used the bag trick to hold the bolt. Whilst doing the left, again with the bag trick, the bolt slipped out and has dropped down. Is it retrievable? If so, how does the trim get removed? So far I have removed a screw and got it part the way out but it is fixed up top. I don't want to break anything. Once that's out the way, why else do I need to remove ?

Thanks
