Quick question regarding roof rails: Is the package that Atlantic British Limited (roverparts.com) offers for roof rails (part numbers LR055273 And LR055254) the short rails or the long rails? I think I've heard both mentioned, but I can't exactly figure out what is what. Is there a major different to functionality? I'm not looking to do any overlanding, just want the ability to put a cargo box on the roof. Thanks! I'd post links, but the forum doesn't seem to like that.
