I made the decision to stray from the drawings call out to install rivets in the majority of the floor panels and I installed nutplates on the floor ribs to make the floor panels removeable. It turned out to be a back aching exercise that was pretty time consuming. I got most of the fwd nutplates installed, Had to order more single lug nutplates. I still need to open the holes in the baggage compartment and install them there too.
