I put all the bolts in and the screws. I used some long needle nose pliers to reach in and put on the washers and nuts. Not sure yet how I'm going to torque these nuts.
Although this shouldn't have taken a whole day, it did. I kept checking and screwing around with bolts, washers, dropping stuff, etc. During this work, I used my fuselage rotisserie by turning it from its side to up side down a few times.
