Can anyone explain how to attach the headliner panel to the upper sunroof? There are two springs and two clips. This would seem easy enough to puzzle out. However there is no obvious attachment point for the springs and the metal clips appear to be able to attach in three different ways. So, where do the coil springs attach and do the metal clips hook on the straight edge, center, or the "U" shaped edge. Anyone who has dissassembled the sunroof should know what I am discussing despite my poor ability to elucidate. I have exhaustively searched the 700/900 FAQ and no one addresses this in any detail. Please help, this is the last step in overhauling the sunroof!
