How tight should the side bearings be

I have a 73 challenger shop manual (not owners manual) and it does not mention any torque for the carrier bearings. It shows how to rebuild but no spec. Like 69mope said they use a spanner wrench. I have the specs for the bearing caps and adjuster locks just don't know tight to make the carrier bearing. I would think as stated 75 ft lb would be good if I can measure it.
