Finished installation of the wing root end nut plates except for some K1000-08 nutplates which I didn't have (but were in my mail box when I got home).
Cut the 1/4" slots in the inboard ends of the T-405 fuel tank attach angles per the plans. Used a dremel cutoff wheel to rough cut them and then used files to open them up so a 1/4 bolt will slide through it.
Installed a nut plate on each of the F863-1 tank attach brackets for the 1/4 inch bolt that will attach the brackets to the fuel; tank angles.
