Final assembly of vertical stabilizer and rudder cables. Tightened and torqued all 10 mounting bolts on front and rear vertical stab spar attachments. Installed rudder stop block on rear spar attachment. Installed rudder horn on rudder post. Installed rudder cables to rudder horn. Ensured cables were routed properly on all pulleys. Attached tailwheel steering spring, cable and S hooks to tailwheel. This is definitely a 2-person job as the stab mounting bolts and rudder horn are very difficult to access and tighten due to confined space. It's really starting to look like an airplane again.
