s10 to 49 Olds
The first picture is correct. 8 to 10 degrees. If you go 10, check for binding in the upper ball joint to spindle area.
Second picture. That is not an optical allusion. the mount is not parralel to the frame, neither is the lower. Exactly how much angle will be a funtion of how much positive caster you build into the static setup. 3 degrees is a great place to start.
Having a gauge is a big help. Not sure I understood your camber specs. I mocked mine up at 0 camber on both sides. Things have a tendency to change with the full weight of the vehicle out on the tires and tire size can change it. Starting at 0 is safe.
