Clecoed in both seat bases plus the side tunnel pieces...riveted the seat belt doublers to the side first, leaving the holes where the seat base rivets empty.
Got it all in place...lots of hand riveting inside the runnel, no other way.
Got the passenger side done.
You can sse at the aft end of the tunnel where I added .063 doublers to each side...this is for the divorce of the elevator from the torque tube...wanted to strengthen that area as the elevator bellcrank is going to get anchored in this area.
