408 How do I remove the glovebox?

[dwomby]

I found 4 screws. two on each side of the glovebox that I removed and the glovebox moves back and down but then gets stuck. It looks like one of the air ducts to the windscreen defrosting slots is in the way but that looks like it would be very hard to reattach. Is this duct the only obstruction? I had expected the glovebox to push back then move down and out in the footwell.

Thanks
