Joe- The Addco bar has a standar swaybar type u-bracket whichwraps around
the lower bar of the vertical link (where the shock mounts). It's then
bolted to the eye on the end of the bar (i.e. the eye is centered inboard of
the vertical link bar). It is then attached to the frame at the furthest
rear end of the frame by means of a u-bolt fed thru 2 holes drilled in the
frame, with the swaybar cushions holding it down (actually up) to the frame.
I see your point about restricting the action of the springs, but that
seemed to be the problem with ours, it would overreact to inputs when the
rear started to slide out, thus causing the car to spin abruptly in the
opposite direction.
