luggage

Managed to knock the end off the big cassette that holds the retractable dog guard/luggage cover on my W124 estate. the spool holding the guard & cover came loose to the sound of whirling, unwinding spring type things! Can't figure out how to get it all back togeter and re tension them so...

Does anyone know if there is a part number for an original MB luggage net for the W202 boot? It really annoys me when stuff slides around the boot and makes noise (made worse as I have my ski hatch open for my sub). I am after some sort of elasticated net to pin bags etc down to the centre...
