JB Weld, with a little thin reinforcing in the recess on the back is worth a try. Very good welder could possibly braze it, but a lot of times the pot metal just melts away under heat. Sounds like first order of business is to take some time to check nuts and bolts for tightness to see what else the PO did not tighten down like cab, bed, fenders, mounts, etc.
