When assembling the right sill we realized that we were missing one part; the rear part of the hot air duct for the rear passenger floor.

Thanks to the kind help of a true Citroën enthusiast we found a used part to use as a template for producing a new air duct. These rusty remains of a 1957 DS19 has been copied and a beautiful new hand-made air duct is now in place!

The air duct is taking shape...
