got my 36 high cab torn down to a bare frame. the frame is severely bent. I'm going to have to remove all the crossmembers and put each of the frame rails in a press to straighten them. I need to know, are the sides of the frame rails supposed to run straight or do they have a curvature to them? in other words if I were to lay a bare framerail on its side, would it lay flat. also what other year frames have similar deminsions? anyone have any pics of straight frames?

thanks, John

it's not a brick, it's cruise control.
