Anyone know if the factory side bars for the 2003 discovery rails are still available? Maybe you might know of something low profile? I'll be using the thule hullivator system, but taking it off when i need to get my vehicle in a parking garage with the 3" lift and tires. (including mounted side rails)

 

Can't answer your question about the rails being available, but I can say you are going to love having the Hullivator for putting a kayak on top of this truck...Makes it so easy!

 

I recently bought a used set for my 2000 disco on eBay, perhaps you can find a decent set there, cheaper than new, if new is still an option for your vehicle

 

Were you going to be selling your current roof racks when you find new ones? I'm on the search for either extension for the 2003 Discovery existing rails and stock cross bars. Any idea where I can find them?
