Hi, just bought a towbar off e-bay, (Land Rover part no. STC 7996). It's the type with the detachable swan neck but I didn't get the key with it. Does anyboby know where I can get one? Also I don't have any fitting instructions with it; do I have to remove the bumper to fit it as I can't remove the swan neck. Does the grey centre panel need to be off with the swan neck fitted?.
