Sounds and looks more complicated than it is
Ray,
I have been reading blueprints for a living for about 55 years, and this is a little confusing to me as well. I am in the same boat as you, I dimpled all the holes too, but did remember to leave the rivets out.
The view on drawing 38, over on the right side, is what we used to call a "developed" view, in that it essentially takes what is actually a curved or bent surface, and rolls it out flat. So, the view of the left wing skin is as if you removed the entire skin from the wing in one piece, unbent the leading edge, and laid the whole thing down flat with the inboard end to the right, outside surface up, the top trailing edge toward you, and the bottom trailing edge away from you (i.e., at the top of the drawing in the view on dwg 38). It is a little more confusing then because all but the last couple of inches of the right (inboard) end is then "cut off" and discarded, leaving the view shown on dwg 38. On the tank portion of the drawing, the plate nuts are all in new holes that are not yet in the tank skin, so no worries there about anything you did or did not do with them. On the holes in the skin rearward of the spar, they will be opened up for the no. 8 screws, which will remove most or all of the dimple, and you will then be re-dimpling or countersinking for the AN509 8R8 screws. To orient yourself a little better, note that the screws on dwg 38 that are shown as small triangles are the existing most inboard screws on the tank skin, which will be removed and reinstalled as part of the attachment process.
If you go to the top center of drawing 38, look for Section GG, and it will give a better picture and more insight into the orientation of the platenuts and screws, relative position of wing and fuse skins, fairings, etc. This view is looking forward through the left wing root.
Hope this helps.
