I am working on my 79 Wide Track Cherokee Chief. It am swapping transfer cases. It had a Quadratrac and I am going to a transfer case with a centered output. The jeep will have a 4" lift in the end. I was thinking of going to a centered rear diff that I have in a J10, but according to my measurement the J10 rear axle is about 4" wider than the current Wide Track axle under it. By rough measurement the axle out of the J10 seems to be about the same width as the front axle. I know I would need to move the spring perches on the J10 axle, not a big deal. Has anyone else run a rear J10 axle on a wide track Cherokee and did they have any issues? How did it look?
Also, I forgot to mention that I am going with a custom rear gas tank, so the fuel tank will not be in the way. And from the pics I looked at on my old Cheif, it looks like adding 2" per side on the rear axle width will actually improve the look.
