EDOT Environmental Discs of Tron assembly help!

I have an EDOT in pretty good shape yet I have never seen the back
assembled. A friend with a truck delivered it from Phoenix and in
order to protect the back glasses and the marquee, he took it all
apart. it went straight from his truck to the repair shop, after
which it came to my house. I have both back glasses intact and the
marquee, but NO metal bracketing to hold it all in place. I've looked
at the manual but can't find what parts are supposed to be there let
alone what they look like. can someone please let me know what I need
to put this together - send me photos of the pieces, sell me some,
whatever! My friend's truck is empty and the repair shop claims
ignorance and with all the stuff in there it would be finding a needle
in a haystack... worse when you don't know what the needle looks
like.

It's remotely possible that backing brackets didn't even leave phoenix
but that guy has since moved so no luck happening there.
