TQW Third Brake Light Question

[Steve Jensen]

The red lens has popped off the inside of the third brake light on my TQW,
so I am flashing white light at night when on the brakes (one of my pet
peeves, the 80's Fords all seem to do this...grrr).  I want to fix it ASAP,
but cannot for the life of me see how the black plastic shroud comes off,
and Mr. Bentley ignores the wagons.  Tried prying from the side but I'm
afraid I'll break the thing.

Anyone care to share how it is removed so I can cement the red lens in
place?

P.S. Thanks to Phil for showing the Treser taillights on a black wagon (like
mine), yet another part made of unobtanium I would like to have!
