Drilled out the stiffener on the left side of the roll bar and then applied a break to the skin edges, had my usual luck with the edge break pliers and it looks fairly poor. Drilled all skin to canopy holes #27 then dimpled for a #6 screw. THe top center hole required creation of a set holder in order to dimple. Took aft canopy to basement for storage. Cleaned plane interior under covers then got tail ready for more fairing work.
