Installed trim servo. The book has you use the third hole up from the bottom of the stab brackett and drill the bottom right hole for the servo. this put my hole in the steel weldment with no room for a nut. Since I drilled a small pilot hole I just ran a Die in and threaded the bottom hole. Installed a 6 pin molex connector on the servo and wire and routed the wire through the tailcone. Clecoed the top skins in place then riveted.
