Rear Retractable Parcel Shelf

[G7enn]

Good Morning, N E one else had the problem of the retractable parcel shelf not retracting back into the holder cartridge. This item use to work in the same way as a retractable seatbelt. But now the tension has gone and the item will not retract. On each end of this item there is a small screw and a couple of small grommets. However with all of these removed the ends of the cartridge do not appear to come off. Does any one know how to remove these ends and is the item repairable? Any help would be greatly appreciated.

Kinds Regards
