Skooter, your bracket looks like it was taken apart/modified to reposition the plate and light to some previous owners desired place. The original vertical and cross plates were riveted together, but yours appears to have been welded at some point. Whatever works for your truck is fine. Just don't recall ever seeing a mount like that before.
Makes no difference to me, it's just interesting because it appears original to me partly because of the rivets. Don't believe it's welded, although the thick flaky rust does look like weld spatter. The horizontal piece that bolts to the truck has a lengthwise bend I haven't seen in modern repops. Who knows, it could be from some other brand truck of that era.
