This was a difficult decision for me - Do I start riveting the top skins now or leave them for a while? After some research I finally decided that I will rivet the F-775 rear top skin and leave the F-7112 aft top skin off.
First step is to rivet the F-787 stiffener web to the F-707B angle clip.
Next the F-775 rear top skin was cleaco'd on and then I began riveting the aft most rivet line. Always a little tricky to rivet around a curve, but I managed it just fine.
