Step 4: Machine countersink the nutplate rivet holes in the F-1201H Upper Fwd Fuse Doubler. Dimple the screw holes in the upper fwd fuse doubler and F-1201A Firewall Upper for #8 screws. Cleco
then rivet the upper fwd fuse doubler and nutplates to the firewall upper.

I notice that in Fig 3 only 2 screw holes area called out for Dimpling #8. Should all screw holes in the doubler be dimpled?
