Here is a picture of the rear crossmember. We notched the frame to set this 3x3 tubing into it. It is fully welded all the way around and the tubing is the exact distance of the frame rails. So it is
solid.

You can see the bondo nightmare the previous owner left me. Atleast it will make it easy to hide the weld when I do the body work.
