When I've assembled rear ends I've run into this issue. If you are sure the radius rods are straight, then assemble the radius rods to the front bolt through the torque tube
with the six bolts holding the torque tube to the banjo at the pinion loose. After the front bolt is through both radius rods and the torque tube, start the nut.
Then tighten and wire the torque tube at the pinion, and finish by tightening the front bolt. This puts the torque tubes into compression and they will not flex. Don't be tempted to loosen the backing plate bolts, those are a tight fit through the axle housings and there isn't any wiggle room there.
This is the way Mitchell advises assembling the rear end when you install an overdrive.
