How would I replace that beam thats on the frame rails beneath the rear bench?? There is a part of it thats rusted. I'm sorry I do not have a picture.

Is this piece about 18 inches long, 6 inches wide, and perpendicular to the frame rail (number 8 in the pic)? If so, that's called a "rear cab mount" in the LMC Truck parts catalog and the RH and LH rear cab mounts sell for 25 bucks per .

I'm going to be replacing some of these parts on mine soon, or to be more precise, I will be paying a body shop to do it for me, along with a bunch of other bed and bed side panels. I love to wrench, but MIG welding body panels and painting are mind-boggling, jedi mind-trick voodoo to me.
