I set a xj6 cage inside my frame rails on my 1/2 ton today and I got super excited because it almost lines up perfect. I am planning on doing a c notch to the frame in order to get it lower. And when I do the c notch I am thinking of making the frame fit the angle of the jag cage mounting supports as it does in the car. So the jag rear will be a bolt in set up as in the car. Then if I want to change out to a 12 bolt or 9" later there is not much fab work to remove and replace.
