Prepped the left wing for attachment: trimmed forward left fuselage T-bone, match drilled truss attach fittings and up drilled 7/16” spar bolt attachment to truss fittings. Loosely remounted fittings to wing. Upsized forward wing spar attachment holes to 3/8”, by progressively upsizing the holes and finishing with a 3/8” reamer. Rounded strut-fuselage attach fitting to clear the welds on the fuselage fork.
