the first 5 pics are of the front torque boxes.
The rest are of the rear torque boxes.
Now before anyone says anything about there being no holes in the rear ones, I popped the studs out of the leaf spring supports, and bolted them back in place, then welded the washers and nuts in place. When I'm done using the leaf springs to locate the rear end I will just unbolt them and the washers and nuts will stay put never needing to be accessed.
