JVC063 is correct and the photos he has supplied are correct.
If strict Ford factory originality is your goal, the blackout is definitely 20mm (approx) stepped up. The black only extends to the guard/beaver panel seam.
The beaver panel should not be painted black along the bottom. Only the body colour.
Attached photos below are Ford factory correct. (sorry the photos are not so good quality. The camera batteries died soon after).
However we all have our own personal interpretations and preferences.
