Here's mine. I used 2x6, cut it to follow the contour of the floor then welded a 3 3/4" flange on it and spot welded the floor to the flange much the same way our trunk floors are attached to the frame. I drilled a 1/2" hole at an angle through the new rail welded in 3/8" steel pipe, cut and ground flat, this is how my emer. brake cable runs through the new rail. I also made torque boxes, did'nt get the fronts in the pictures. still have a little left to do.
