Continued the fit lower longerons, drilled to WD-603... Fitted F-902 to give everything a bit more stability. Fabricated and fit the F-684L&R gusset. Everything is fitting together just fine... The only issue I have run into so far, I had to fabricate another F-684L due to edge distance. It was my fault, since I did not check the alignment with the firewall before match drilling to the F-713 Longerons. Anyway... I just made another one, and it fit nicely.
