Thanks, everyone, for the advice.
I decided I'd try to fix the bend.
If that didn't work out, I'd cut it off and (if needed), rivet an aluminum angle inside.
If that didn't work, I'd buy a new sheet of aluminum and start all over.
Fortunately, I didn't get past step one.
I annealed the bend with propane and a sharpie. With that much aluminum, it took a lot of patience to get the heat into it with propane. I couldn't burn the Sharpie off from the other side, as I found recommended, so I hit it from both sides. I was tempted to get the oxy-acetylene out, but stuck with it.
I then bent it flat, by hand, with the broad leg in an improvised clamp. Then a plastic hammer to get it flat, followed by a light tapping with a steel hammer to get the last kinks out.
I meant to anneal it again at that point, but forgot or ran out of patience or something. In any case, it bent up just fine in the brake. My alignment is much closer this time...certainly close enough for the foam and clamps to accommodate.

The black mark is where it lined up pre-fix. The blue line (bottom) was my target alignment after the fix. It ended up about 1/16" low...certainly within tolerance. The front was marked similarly. It looks like a big, nasty gape below at the rear, but it's not that bad, really.

Next up I need to do the latches...but not until the side skins are installed.
Thanks again, everyone!
