Hi
As far as I can tell, the radius arms themselves stayed the same or similar, but the attachment to the axle was modified to have two fixing points one above the other, rather than one. The idea was presumably to reduce the twist of the front axle beam under braking torque, which tends to act against the brake cable tension and partially lets the brakes off. If Austin saw fit to do this mod, you can be pretty sure it was needed.
