On my NAF chassis I have a rear cross member that my rear shocks attach to, aft of and above the rear axle.
I used a Speedway Engineering sway bar setup (“torsion bar” bar with aluminum arms) which I attached to the same rear cross member with the arms running forward and attached via links to the Ford 9 “ rear axle.
I sized the sway bar using standard sway bar calculations and ran a sway bar that is 75 to 80 % the stiffness of my front sway bar which is an MGB 7/8” sway bar.
Great handling with no body lean but does not make the car overly stiff. Depends on your spring rates of course.
Check out the pics in my Gallery.
