I happen to have a set of genuin roof bars for the above model car I know it's not a range rover part but some one may be able to make use of them. Fitted and used once they came with my new roof box you clearly would need the roof rails for these to attach to the car.

Part number : LVPLCR0131

currently listed on main dealer web site as out of stock prices at £253:50 so £100 buys them prefer collection but can post at additional cost
