Does that piece curve inwards as well as have the flanges that curve? If so, you will need to form curved flanges....then stretch the first flange, and shrink the second one. You can form curved flanges with a crescent wrench adjusted to fit the sheet metal loosely, and bend gradually a little at a time all along the flange....tune up with a hammer and dolly.
If you don't have a shrinker and stretcher: To stretch, you can use a small faced hammer like a ballpeen...start at the edge with harder hits and blend towards the inside with slightly lighter hits. You can do this over a steel plate or anvil. To shrink, you can form tucks in the metal and hammer them down over a steel surface. There is a picture of this in this album: http://allshops.org/cgi-bin/community/comm...d=9980191607382 There is a picture called tiny shrink at the bottom that is done on a flange.
