Wing bolts took 4 hours, 2 men, not bad. Had to grind a wrench down to fit in the tight space. Borrowed Ken's "wing tool", consisting of 1/2" pipe and fittings to create a "bang bar" to hammer against when needed. Froze the bolts prior to insertion. Went very well. After wings permanently mounted, installed fairing. Will remove and paint at a later date with other fairings.
