Note that the F-1015A-R/L seat ribs have a joggle joint on the front edge with the F-1004D-L/R bulkhead where the rib will be on the inside of the outer flange of the bulkhead. Similarly, the upper portion of the front edge of the F-1018-R/L rib goes inside of the F-1005C-L/R bulkhead however, its lower part goes outside of F-1005C-L/R.
If you haven't updated your plans in a while, ensure you dimple the #40 holes in the web of F-1015A-L/R.  There was a revision on page 26-5 in July of 2021 that added this as step 1. However, don't dimple the holes that are on the flange of F-1015A-L/R which interfaces with F-1004D-L/R.

Consider at this point whether you need access holes in the F-1017 under-seat ribs for conduit and/or antenna wiring. Many builders cut holes in the F-1017 ribs for conduit passthroughs.  These holes will be much easier to cut at this point.

Also consider marking and cutting/installing antenna doublers on the bottom skins in this general section.  This will be much easier now than later, when the seat plates are permanently riveted in place.
