Interesting update on "crappy" repro fan shrouds

I just purchased one through Hoover, I didn't get it yet, but I was wondering if anyone has a picture of where the warping occurs. Is it possible to install a metal strap along the top and bottom egde, paint it to hide it (if that's where its warping) to keep it securely tight against the rad support?

Mine warped at the top. Kind of hard to tell in the picture but it sagged around 1/2":
