I'm working on aft fuselage and step 1 of the instructions on page 10-07 state "Dimple the #30 holes in the web of the F-01412A and F-01412B Bulkheads ..." except for the ones indicated in the line drawing. In step 2, I am to machine countersink the aft side of the F-01412D Tie Down Bracket. I accomplished each task but when I placed the TD bracket on the bulkhead, two #30 dimples on either side of the bracket keep it from laying flat. See arrows on photo. Any idea?
