Better than some I've seen - you have all the structure and the captive fittings.
When you make the new ones, prime, paint, and seal them, then line the bottom with putty formed into a little channel to the drain point.
When you get to the drain hoses, the originals were too short and finished inside the double skin, so extend them a bit so anything that drains come out of the hose below the level of any sheet metal.
Of course if you live in a desert, just put those ones back ...

Nice work Zepher! And thanks Gordon for the suggestions. I will certainly incorporate your ideas.
I do not have a sheet metal brake, so my plan is to weld 1.75 channel together, tack in the window guides, and cover the open back with another piece of sheet metal. I found that 1.75 od, 16 gauge, square tubing has an id of 1.620; the original width of the window box channel is 1.625, so I will be giving up .005 thou. I will be cutting one wall out of the tubing to make the channel, and reusing the side brackets.
I will post some pics when I build them.
