Installed aft deck plate and stabilizer brackets. You can squeeze most of these rivets but still need to set a bunch with the rivet gun and bucking bar. I found many of the size call outs (length) are not correct. A few are too long and a few are too short. Common sense prevails when installing these rivets. Once that is done, you mock up the vertical stabilizer and finish drill two #12 holes then remove the fin. The upper side skin then gets clecoed into place to prepart for riveting. I need to wait now for another set of helping hands before these get set.
