After lifting my Defender 2" the passenger side radius arm is now only about 4mm from the chassis. My nearest Landy servicing depot told me an adjustable panhard rod would open it out slightly. Anyone know if this is the right way to go? Or is there more to it?

Hey all. This must have been mentioned before but I couldn't find any threads using the search. I'm after fitting some driving lamps to my roof rack but everywhere I look it says its not possible on the 07 model due to the air conditioning. I would quite happily order the parts and do it...
