The spars for both flaps were pop-riveted to the ribs.
The spars for both the left and right flap were then riveted to the top skins. Turned out quite well using the tungsten bar with the angled end.
Once completed, a shot of primer was applied to the spar for the minor scuffs aas a result of the bucking.
I still have to install a nut plate to hold the retaining clamp which will hold the hinge pin in place after a couple of eyelets are removed in both flaps.
