I can do the math, if I have the right hole (Reference # 6) correctly identified and if the hole in the replacement metal is only 1/4 inch then for FOD measurements I add .125 for the near side measurement and for the far side, I subtract .125 giving me 3.345 and 3.595 for horizontal numbers. That should position the 1/4 inch hole correctly to where the FAM identified a 1/2 inch hole.
