1979 Dodge Van adjustment of rear wheel bearing

This vehicle is a dually partial cab as shipped from the factory. I an rebuilding it.

The full floating rear axle bearing adjusting nut is of the wedge lock type. I have found the torque specs. For the lock washer style (adjustment nut/locking washer/lock nut).

I need the torque specs. For the wedge lock and adjustment proceedures.

I believe this is a spicer 60 rear end but am not sure.
I assume the proceedure for wedge lock would be the same for all rear ends?

Thanks in advance
