if its the infill centre panel, as opposed to the 'strap-on' version, there should be two mounting points on the inner edges of the roll hoops that it slots down into...plus two in the boot lid to stash it.
If you've bought one separately then unless you've got the fitted mounting kit you've got to go and try and get the bits from the dealers....if your hoops don't have mesh infills then the kits not fitted - if they do, then its either there or has been removed?
hope that makes sense..
