Cheers Mark, at least I know what it is now!
You're right about the lack of nuts for mounting but I suppose I can improvise with something.
It's not really worth messing about sending it back for the sake of a tenner and to be honest the Ebay ad isn't technically inaccurate, just not completely explicit!
I've got the retractable load cover but could do with the dog guard too, my pooch has the very bad habit of finding his way to the drivers seat when left in the car for more than 5 mins, little bugger!
I've got the retractable load cover thing (no dog bit), don't suppose there's anyone on here who wants to swap there dog guard/load cover for just a load cover (anyone with no dog)? And cash your way of course?
