The instructions say to dimple the #30 holes in the side skins except as shown in Figure 1. Figure 1 helpfully circles 6 holes around the rudder cable exit point and says to dimple those, circles 4 holes in the lower aft corner and says not to dimple them, and says nothing at all about the remaining 4 #30 holes in the aft end of the side skin. Do those get dimpled or not?
