I've searched the forums and haven't found a clear answer to my problem.

almost got in an accident the other day from a driver not paying attention and blowing thru a stop sign, me panicking put my hand up to the ceiling and pushed up, well what I pushed up on was the sunroof shade.

The sunroof glass was closed but the shade was about 1/3rd of the way open. When I pushed up on the shade it must have popped out of whatever track or way it slides up there, I don't think I broke anything up there but now I cant get the shade to move further forward than 1/3rd of the way and it does move side to side a bit so it's definitely off the track. Does it slide into the track from the back? Any ideas on how get it back in its track? Any way to do this without too much of a pain?

 

Here's a link to a schematic. I think you pushed it out of it's track too much. Generally, to get to replace it you'd have to remove the whole top headliner...

Here's a tutorial on removing the headliner, if you read through it, the OP says the sunshade frame is riveted....
