The factory sent replacement stringers for the fuselage join but they are the same as the ones I have so I will return them. At PGCs suggestion, I clecoed the forward skins in place to check how the join will look. It's not too bad but the stringers in question still bind against the rear spar vertical "z" sections opening the seam. I will need to open the spaces in those channels for a better fit. As I needed to install the centre console to get the correct alignment for the forward skins, I decided to cleco in place as many parts as possible.
