There's not much to it. Use a round file to carve the notches and if you care about mechanical authenticity, add material to the top of the frame.

Use Google images, there's lots of ways to do it.

On the one on one pick ups part of the frame would be cut away and reinforcing plates would be welded or bolted onto the frame to strengthen the frame and provide a preformed arch or a "C" section shape. On passenger cars they would often cut a "C" notch in the frame and the smarter ones would add a basic round reinforcement to keep the frame from folding. Where room is available often the frame is cut all the way through and a bridge or arch is formed out of similar material as the frame. This method would require modifications to the body floor for clearance.
