You MUST have something in there to take the forward/backward loads on the control arm. Take them out without changing something to compensate and the first pot hole you hit will be the truck's last.
They use an A-Arm on the B2600 that uses two mounting points on the frame that are about 14 inches appart or so. Like Chris said this keep the control arm on that truck Triangulated without the need of the radius bar.
