I'm using a Sterling 10.25 from a '92 F350. Mine is a wide dually pickup type. You most likely need one from a cab/chassis dually, which is a bit narrower, and more common. I had to move the spring pads about 1 1/2" or so. That was easy, and I'm no pro. Now I have 4.10 gear ratio. I have gone 65 a few times with no issues. I think it used to top out around 45-50 mph.......

timken/rockwell B100 axle. You have a 5.83 rear end. They made a 5.14 diff and also a 4.88 I had the 583 and was able to buy a 5.14 That rear axle is common in studebaker 1 tons and some dodges. International used a similar rear with the same bolt pattern for the rims, but the diff is a total different diameter. If your trying to keep the original rims, you'll have a challenge, but keep looking.

Depends on what you find. You can pull the diff without taking the wheels off. Yank out the endshafts and then you can remove the diff. It comes out as one unit. A tranny jack or a good floor jack helps. That diff is heavy. If you can find a whole axle of the same type, you'd have some spare parts for the long run

Hey Guys,
I know this is an old thread but It mentions something of my interest.
I am Looking at at dTa b100 rear end(dually) With a 5.14 Ratio,I was wondering if the Gearing is to high.
I want to use it on my COE(providing I find 2 front wheels and having them fit my Front end)
engine is a late small V8 and automatic.
Thanks guys

Depends on what you are doing. If your not worried about originality, find a newer 8 lug dually rear with a better ratio. My truck will cruise about 55 with that rear, but I'm like at 3,300 rpms. That's with 17.5 tires

Thanks man,I just love the look of the old wheels.
The Rear end has some 15" wheels and I was planning to use those size tires but I guess I would only be doing 40mph at 3500 with them
