Set the wing spacing with F815 and the measured distance of the wings. Both wings were very close to the same dimension. 26 19/32" and 26 18/32". Had to move the F815 distance just a tiny bit to get the dimenions correct. Drilled the holes along the rib and set this distance. Installed the 426-3 keeper rivets to hold the position. So far everything is looking good. I have to tackle the bending of F823 and I'm not looking forward to that process.
