Thanks everyone!!!! The arbag suspension was very easy, I took the coil over shocks out of my mustang II suspension and replaced it with air bags ( they fit in perfect with no cutting and could be changed back.) I removed the leaf springs in the rear and installed a 4 link. I mounted the air bags to the frame and to the lower 4 link bar. Add a air tank, 6 valves, and 3 switches, some air lines to the bags and Wha La!!!
