				| Put in the F-915s in place
 I have to remove the bolts in the aft ends of the ribs where they hook up the F-605C Bar Doublers. After drilling out the holes in the ribs, I temporary put the bolts back on, but only hand tight. Then I started drilling holes into the ribs, spacing the holes out about every fifth hole. Then I went back and drilled all the rest of the holes.
