It was easier to track all the seat ribs by keeping them clecoed to the bulk head, but to finish the floor I removed it and riveted the floor in place as per the directions. I had to use the hand rivet tool in a couple tight spots. Also when I used the pneumatic puller on the CS-4 (counter sunk rivets), I ended up with a huge bure as it pulled metal up into the tool. It looks like the opening in the tool is to large. So I found a flat piece of steel (~1/8" thick) that I drilled a small hole through, just slightly larger than the mandrel on the CS-4 rivets. Then I put that between the puller and the rivet and it came out nice.
