do you know where I can order all parts required? I know you have yours for sale. Also I cant find a 2.4l liberty anywhere.You need front and back 4 10s. Yes the ratio must match. You will need to find a 2.4 gas liberty in the junkyard in the U.S. They are the only ones that came with 4.10 gears here. And you need the front and back differentials.
