I believe there is a "special" bracket. Meaning the Durango nor the Dakota will work. I also believe that it's held in one top, one bottom with a 10mm that attaches also with 2 10-mm nuts up top. Look for the two broken/rusted studs that probably let to the ultimate removal of the originals.
Those are the aftermarket versions of course but they should give you an idea on where to look for the mounts.
