Pitts S1s rebuild

I am rebuilding a 1972 Pitts S1s and am replacing the worn top wing attachment brackets. Maybe some one more knowledgeable than I could explain why the aft brackets, part no. I-410-13 require the plywood wing centre section skin to be cut away to enable the landing wire clevises to be fitted? It seems to me that if the landing wire holes were positioned slightly lower on the bracket the clevises would clear the structure with no need to gouge out the centre section skin. I attach one of the photos on Steen Aero's site which shows just that. Am I missing something?
