I recently bought a 2001 suburban and the previous owner mentioned a slight leak from the sunroof. After getting it home and looking a little more there were a couple of issues, first was a small tear in the sunroof gasket and the other was that I found the rear drain trough pushed all the way to the back between the roof and sunroof frame. I can't seem to find any pictures or examples of how the rear drain trough attaches. Here are the pieces I found after taking out the headliner and I think I have figured out that I needed to straighten the bent guide arms and also how the brackets attach to the trough although I still haven't figured out where the "guide arms" attach. I spent some time searching but I couldn't seem to find any pics of how this trough attaches. Also, I know there is a piece broken on both left and right plastic brackets that attach to the trough and I am still thinking about how to "repair" those by potentially making some brackets and using epoxy to affix them but any advice on that would be appreciated as well.
