Rivet the front floor stiffiners to the front bottom skin. I really did this over a couple of evenings. the trick was figuring out how to get it done alone. I could lay the backrivet plate over the holes and placed the sand bags I made for the flaps on top. With about 30 lbs or so of weight on top of the backrivet plate I didn't think it would move on me. I was able to back rivet from underneath and aside from banging 5 rivets and then having to move the sandbags and plate to a new position it when pretty fast. Spent about an hour on the first two rows and came back the next night and did the other two rows. It came out great!
