...Drilled wing incidence...We leveled a/c after reaming more material off top of R wing slope above rear spar. The horizontal R wing measurement was 143.5 and the L 143.75 and there was 1/8" or less of fwd sweep and it was even so Dave drilled a 40, then 30/then 3/16 then 1/4 and reamed to 5/16 on each rear spar and we have our 5/8"ED. Praise the Lord! I drilled out and installed 3/16 bolts or R aileron bracket and attached aileron pushrod at aileron. I traced bottom of skin on wings for nutplate cogitating.
