Checked positioning of stabilizer for alignment. Using rear spar bkts and stabilizer spars. Fwd spar is 84 mm and rear spar is 80 mm, so using a 2 mm shim on blocks on the spars checked for level. With stabilizer brackets sitting on longerons eveything was set, no positioning requird. Had put shims under fwd bkts to ease the tension on the frame. bkts. All worked out well. Bolts installed and tprqued.
