i should rephrase,,,

does your rover have the small skinny roof bars or the big fat bars?

mine has the fat bars. if you have the smaller skinnier bars then there is a clamp on for them.

i was thinking on my rover,,,

 

they're pretty skinny..about 5" circumference.

 

Yes it is true you can not have the larger bars on the top, i.e. 2004 disco. But this will give you a good look at it with a Kayak on top! Sorry for the bad photos but I did not have a good camera with me when I went this time!!!
