I have the parcel shelf with integrated blind in my S2 Xantia hatch. However, the cords which support it on opening the hatch are knackered. I have removed the two plugs from the end of the tunnel containing the cord, sadly one was damaged in the process as it was very brittle.
Here's what I have left:

Question - is there a repair kit for this, and can it be bought online or do I need to visit a Citroen dealer? (breakers yards don't have any Xantias at the moment)
Cheers in advance,
Ainslie
