Topic of rear sway bars was discussed recently. Do a search under Don Scott, or DV. Anyway, it depends on the design of the sway bar, and the suspension it's used on. 4 link solid rears lend themselves to this setup. Many rear sway bars, including late Mustang from which many Cobra rear suspensions are derived, attach to the lower control arms only. The arm is bolted at two points per side, allowing it to twist. The torsion of the bar keeps the wheels and body level during cornering. It's designed that way. Virtually all late '60's - early '70's with OEM rear sway bars were setup this way. (Olds 442's, some GTO's, and big block Chevelle SS's) Take out the 4 link, and put in an IRS (or leaf springs) and the sway bar would have to be attached to the frame, with only one attachment point on either side of the suspension.
