They do come up on e-bay from time to time & are expensive, but dealer price is outrageous! I opted for the "sports bars" which are cross bars that use the roof fix points & can be moved around between the three positions available (so that you don't have to have one over the sunroof opening) They can be fitted & removed in minutes with an alan key .
I do have a brand new pair of landrover cross bars that grab onto the fixed long rails if that's any use to you (bought in error!!) when you track them down . Rimmer Bros . might have them IIRC

Thule do a crossbar that bolts on to the fixings in the roof channels (like the Land Rover genuine sports bar ones) but check the prices first you may find it is cheaper to buy from Land Rover!!! As with Thule you have to buy all the bits individually and this soon adds up i.e. £150 ish when you have to buy the crossbar, foot kit and adapter kits all separately!!
