How do you straighten a k-frame off the car? Is it worth it?

If you managed to bend a K member, I wonder what happened to the car.
My best bet would be to strap it back into the car it came out of and then put the whole car on a frame machine to straighten it out. But like was mentioned above, if you have to go to those lengths, then it might be a goner.

I have a K member I can measure up that came out of a very straight car with frame connectors so I am almost certain it should be straight or at least within factory specs. It is possible that these K members came a little tweaked from the factory because tolerances were so loose. Ive seen countless stories of people here noting that measurements all around their cars were 1/4 inch or more away from factory spec because of loose tolerances.
