8.75 and 8.25 ready to go in (almost)

What you need to do is a google search for the length of your axle, and then the length of different Chrysler axles.
Of course anything can be done with shortening and custom length axles.
Dr. Diff has the axles, or can make them any length you need.
If I remember they run about 300 a set.

Then you come up with stuff like this.
An accurate 8 3/4" rear axle width list

And this.
about 55.5 quick rough measurement.
From here. https://www.jeepforum.com/forum/f28/looking-kk-kj-rear-axle-widths-964526/

So the difference between the A body Mopar rear at 51.5 and the Liberty rear at 55.5 gives 2 inches difference per side.
This can be done without cutting and shortening if you get wheels with the backspacing required.
Or cut 2 inches off the axle.

It definitely takes some investigation, and I NEVER take one or two search results as the definitive answer.
Hey Trailbeast how will you adapt emergency brake cables to rear disc set up?
