Tonight I started by drilling former #5 to the turtledeck skin and then on the bottom to the tailcone assembly, pretty easy so far. Then it took me quite a while to figer out how I'm going to drill the clip between former #5 and the slpice channel, looks like an impossible job to do. Then it came to me, just uncleco and lift the left half of the turtledeck and you have full access to the splice channel and clip. Done. Finally I also drilled the left forward former #1 to the turtledeck. Pretty easy but you need to be carefull to keep it all aligned.
