I installed the seat belts both forward and aft, ill probably take them back out so I dont get sika on them during the canopy install but i wanted to work out the issues now while im waiting on my landing gear and finishing kit to arrive. I also worked on getting the aft upper fuselage skins on. The left skin went on smoothly, I only clecoed it so I still have access back there if needed for things like redoing the ELT buzzer and the static port install. The right side skin was a different story and I had to take it off and reinstall it about four times. In the end I could get the top and bottom row of rivets to align and most of the ribs to align. One rib just didnt want to match up so well. I had to have a helper while i reached in and pushed/pulled the rib while my helper clecoed. I elected to rivet the right skin in because I was having problems with it and didnt want to take it back off and fight with it again to get it as good as i had. Also I had to be careful where the front of the two skins matched up because it was trying to bulge up in the center where the two skins meet. I had to be cognizant of that and work the skins down on each side to get rid of that bulge. In the end I am happy with how it came out.
