A) Ford's policy was reportedly to replace the entire axle, not just the diff. It would seem that some industrious dealer/tech/scrap folks are selling these axles for cheap. I would speculate that some if not all are faulty axles and have 'bad' Torsens in them.
B) Even axles from junked/wrecked trucks could be suspect if they came from a truck w/ an Auto. Not all '01 axles were replaced, only those w/ manual trans' were! At least that is as I understand it..
John, what you did works because you replaced the diff and whatnot. But for someone that's looking for a direct swap w/o replacing the guts..
Well according to the guy I talked to over at Duff over 1 month ago they were working on an updated set of bars. They SUPPOSEDLY had a "prototype" set on someone who worked there 2004 FX4 LII Like yours Neil...now this was 1 month ago...I ordered a set of the AS YET TO BE PRODUCED new bars...however maybe they found the error of their ways by making them for the LII axle as opposed to the 28 spline axle found in MOST '01 and later Rangers that have the 8.8" of course!
So I think I'll call back to "check" on my order and see what they have to say now...I seriously doubt they are going to make a set exclusively for the LII 31 spline rear-end...there are just too few of your guys out there.
However when I call I'll try and get as much accurate info as possible as well as an ETA of these "new" bars and brackets!

Neil.. If you want to order a setr of those duffs, Bri and I could mill up a set of plates like Bob Rez has. Bri Just ordered a set for his 2005 FX4 LVL2. You need a set of those duffs badly after feeling the axle warp on that one hill we went up.

Yeah mines a stock 28 spline so I would only need to grind the tabs.

I seriously have to order a set of these. $70 just has to be worth it..
Didn't you also have to shorten the bracket to prevent it from hitting the underside of the bed/fender?

Ha ha! Yes, I have the "Duff Dents", lol.
If you have the stuff around, the "cut and paste" method I used is very quick. If you want something NICE, Bob's is the way to go. I'm not always known for doing it "right" -- just getting it done is all, lol.

He was referring to grinding the mounting ears to fit the stamped in "relief" in the top plate for the springs, I THINK. I did do that on my original 28 spline install as did most of us who bought the old style bar mounting brackets.
