I carefully mounted the nose ribs, to be sure I was selecting the right version of the 1208 (mostly R) ribs and then riveted them to the spar and to the attach angles. It was slow work to get both to line up properly.
The instructions in the last section seemed to indicate only one nutplate goes on a couple of ribs. It's actually two, judging by the terminology of the instructionsI read today.
After ribs were in place the forward nose rib spar was riveted in place.
