Fitting Side window panels along top so they will swing freely up. One done, one to go. Floor panels all cut and started cleaning plastic off. Drilled to tabs in fuselage. Tried nutplates. Too much work, don't have enough. Will use for door trim only. Mark G says use Tinnermin nuts. Mule Fulton getting them for me. Cost is for window acrylic and fasteners. $140. Tinnerman nuts $20.
