My Daihatsu Copen did not come with a tonneau or opening cover - the piece that fits between the back bulkhead and the folded roof.

This video gives you an idea of how to install the entire tonneau cover assembly - the boot hooks, the bag itself, and the clips.

Daihatsu wanted £400 for this option from the factory. I fitted the entire thing using (mostly) second hand parts for about half that.

The tonneau cover, and back wall assembly were second hand. The hooks in the boot were brand new, and cost the most!

Whilst the rollover bars were off, I plastidipped them red!
