rear diff 46 ford 1/2
thanx for the reply . Im thinking the late 60s early 70s tang, as the auto floor shifter is somewhat installed. how do I get a photo out there to see ? I have digital pics? what about the revs ? I did the wel spin drill a dozen times,and still get 2.3 revs on the yoke per wheel rev. also the rear has 1/2 ton 5 lug pattern.

The easiest swaps into a '46 would be 1/2 ton rears up to '72. Since your tubes are not tapered if it is a 1/2 ton it would likely be '48 or newer. I think they had 2 basic style between '48 and '72. The early ones (I think to '57) were the Dana style where there is a differential cover on the back side.

After '57 they used the 9" rear where the gears are loaded onto the center section which is bolted in from the front side.

If they did an easy swap this might get you a little closer to what it is.

I got one of those rears with my 1st '46 also. In the early '60s the guy I bought it from had converted the truck into a hunting camper. He extended the frame and moved the front of the spring to the rear spring perch. He said that he had setup a double axle of some sort using this newer rear as the drive. He had the frame pretty much cleaned up when I got to see it, but gave me all the parts that he had for that truck. I didn't realize that the rear was "wrong" until I tried to bolt it onto the springs -- the spring pads were welded in the wrong spot. So after a little investigation here I realized that it was likely late '40s.
Since the project has been going slow, I have been buying parts whenever I find them. I now have an ~'72 and a '57 9" 1/2 ton rear. And just recently picked up an original banjo really cheap.
