If you don't get a good picture by this weekend remind me and I will get pictures of mine.
no doubt im trying to figure out if the top part of the bezel slides into the lower marquee bracket. I have a custom caberet that i bought and the bezel goes to the top of the cab. it was originally a vertical cab,I put in a horizontal lcd. i think i can build an area for the marquee simliar to Donky Kong. 
Since it's a custom cab, it probably makes more sense for you to post a picture of the cab.
On a typical Donkey Kong narrow body cabinet, the top of the bezel is held on by the bottom of the marquee and the cabinet. There is a adjustable metal rod which also holds the bezel in place. The lower bracket snugly fits around the bezel and fits into a slot cut into the piece of wood above the control panel.
