I have rebuilt wings using Univair stamped ribs in the past. I have a set of Dakota ribs on the way for a set of Clipper PA16 wings I am rebuilding. I have another set of Tri-Pacer wings to rebuild and am trying to decide which ribs to use. Dakota's rib kit is $500 more, my cost for the set. When I say rebuild I mean everything comes off including the bushings in the wing attach fittings.
