I had to remove one of the rivets from earlier in the build in order to get the stiffener under the fire wall attached. The rest was pretty straight forward. A couple holes needed to be reamed, but that's typical...the only thing I don't like is all the shavings are getting caught between the bottom skin to side skin seam and it's bothering me. Unless I remove those rivets I don't see any way to get them out of there. I may end up just adding a small bead of sealant to cover it up...that's a problem for another day.
