Why a nutplate on the aft side of the rv-6 fuselage fuel tank attach bracket? It's not hard to access so I am thinking about using a drilled bolt and castle nut instead. Has anyone else done this? Also I have wires leading from the front of the cockpit aft past the spar, I think they will be ok under the wing root fairing but it would be nicer if they could be routed through the spar. I am extremely leery of drilling through the spar though; but is there a place on the spar that could be drilled for this? Thanks in advance. Jim.
