I think you might need to look at your packaging requirements. Can you put a torque arm and a panhard bar on a Dana 60? The rear cover might get in the way of the panhard bar. Where is the torque arm going to mount? Some of them bolt to the center section, some weld to the housing.

If you want a back brace on the rear end then you need to figure out where your shocks go and how the panhard bar fits into the equation.
