Broken '65 Dart Wagon Tailgate Torsion Rod

Hey everyone,

My title pretty much says it all...it's not a big deal, but has anyone repaired one of these? It's probably not worth my finding a used one and shipping it, but mine has snapped off at the far end, right before where it anchors in the tailgate. Could I MIG weld it back together and clean it back up? I guess I've never tried to repair a torsion rod before. Thanks for any input...
