Has anyone ever changed there steering box for a quicker ratio unit? I've hear that the 3rd Gen F-body (80's Camaro, Trans AM)Unit might work?...Any Info on this? Is there any modification that needs to be done to use the F-Body Steering Box? or is it a direct swap? Also, I've heard that AGR makes a nice F-Body Unit for around $350...Anyone ever used it? Looking for a 12:1 ratio unit to get a more "sports car like" feel. How difficult is switching the steering box? What's involved?
