some of the bigger rear ends you have open diffs, limited slip, and lockable.
In my case I had to pay attention to a "tone ring" -- in mine it is used for vehicle speed sensor -VSS and is also used for the rear axle anti lock braking.
When I started, I was told it was not possible to buy 3.73 rear gears with a tone ring-- this is a ford F450... I found the same axle in international terra stars with a tone ring, and the ratio I wanted....
To give you an idea in a 14,000 lb rated rear axle... I found 3.73 3.91 4.10 4.30 4.54 4.88 5.10 5.38 5.88
I went from 4.88 down to 3.73 but the transmission, change had a much lower 1st gear also.
I paid $800 for the diff inspected, pinion seal changed, 90 day warranty, and shipped from florida to kansas

Well, in the mean time, I found a company that does insurance chopshop, and they have what I need. It is called Vander Haags, and it is around Midwest.
I also figured that J1708 and J1939 are just plugs to connect into. I have the J1939 plug and now I just need to know/find the software to connect to ECM.
Thanks for the reply!
