straightening Briz bumper

I have a briz bumper that I removed from my shoebox a few years back. I want to straighten and redo it for the front of my pickup. Does anyone have an idea on removing the radius along the length;ie,flattening it. The end rolls will be cut off.The entire length is slightly curved.

 

Clamp it between a couple of 2X6s, drive over it if ya half too!......OLDBEET
