Dakota or cherokee rearend

The Cherokee rear has to have the long side axle tube cut down to the same length as the shoter side, and a second short side axle replaces the longer one.
This makes it fit overall length and centers the third member for 2 wheel drive use.
The perches have to be moved, and the ebrake cable needs to be changed a little bit where it connects to the cables for the rear.
The driveline has to be modded with a matching yoke to the rearend.

It might be a PIA, but you get better gear selections, rear disc brakes and posi track out of the deal.
Of course you have to start with the right year of Cherokee to get the disc brakes.
