This is the work that was done on my Horizontal Stabilizer which included Cessna upgrade modification kits: SK210-125, SK210-126 & Horizontal Stab Upgrade brackets. We also replacmented 8 Horiz Stab Nose Ribs to the heavier part numbered ribs. They were the middle/inboard to the outboard(4 on each side) nose ribs. Thanks to all of my friends for their help....
