Drilled new panel onto the original OneX panel. Also drilled the panel bottom angle support brackets to the top fuselage stringers. Everything appears to fit OK, next process will be to remove the panels and trim away all of the original panel except an outer 3/4" band with the tabs and nutplates installed. Once trimmed I can counter sink the new panel #40 rivet holes and flush rivet the new panel to the band. I'll probably wait to rivet the panel since I still need to drill and cut the new panel for the controls and instruments which will be easier to do with a flat panel.
Also drilled the two rudder pulley assemblies to the forward fuslage vertical angles.
