Removed top clecos in rear skin at ribs #2 & #3 to ensure nose skin would fit down tight on the nose and tip ribs. Duct-taped nose skin down tight to rear skin. Drilled per page 8 of Section 6-T-5 in Asm Gde. The bottom hole location fell right at the end of Rib #2. This location is not explicity dimensioned or defined on the drawing or the Assy Gde so am assuming that the location is not critical since it will be trimmed-to-fit later anyway.
