Riveted most of the nutplates to the angles as per instructions except those that would prevent back riveting the firewall rivets. (These nutplates were riveted with a hand squeezer afterwards).
Back riveted all the firewall rivets except three on each bottom weldment that will have to be bucked due to limited access.
The rivet callout on the weldments is also incorrect and it took a while to figure out that the AD4-6's go in the top weldments and AD4-7's in the bottom weldments because the base is made from a thicker material.
