I bought this off a mate unseen as he thought it was a fender one. They retail new for almost 400 quid and this one is second hand but in very good condition. Make me an offer or I'll be happy to swap for a defender equivalent
It is as in the photos, can't say I've ever seen a disco 3 but it takes the standard air vent screws plus two long screws then it has one metal bracket at the top which I assume fixes onto an existing screw. I'm not at home so can't say for sure but from what I can tell its just bog standard nuts and bolts you need which may. already be on the vehicle
