Drilled the F-644's and primed, then riveted them to F768A. Fitted and drilled top forward skin. I figured out that the F721-A forward canopy deck shouldn't have been drilled until the F768 was in place. I have figured out a fix and it worked but I should have waited. I cut the front half of the F745's off and fabbed an angle to be able to move them inboard or outboard as I see fit. I really want the Dynon's to be centered in front of me and with a tipper you have to move these brackets to allow that..
