You can re-arc them yourself leaf by leaf if you have a sturdy vice and a piece of exhaust pipe that fits over the leafs to act as a lever when bending them back to their original shape.
If you have a hydraulic press it'll work too with less effort, but it takes more time in the press.
Beware of bending over the center hole - they'll break for nothing there.
