cherokee 8.25! will it fit a 74 scamp

Hi I have a 74 scamp that currently has an 8.25. but i also have a 8.25 out of a jeep cherokee that i wanted to use because it is 29 spline and has an aftermarket disc brake setup. i was wondering if it will bolt up and work if i just weld new shock perches! I have 4.56 gears i just bought that i plan on putting in, but need to know what will work first. thanks again guys
