I know a little about them.....
the axles were weird, there were some 1 tons that had a regular toy axle, well not regular...... but they were standard size, and 5 lug (5 on 4.5") had SUA, 8" ring gear. The 2wd I had, actually had the 8" ring gear, but was a 1/2 ton... weird...... It was originally equipped with a W55, and had a 3.07 gear ratio, 22r.
Then there is the full float, big behemoth dually 1 ton.....
