N.A., if possible, I would advise against getting the bracketed ones. too many bad stories about how they bend or break the mounting point. the bracket acts as a lever in a crash. I know some people have crashed with them and had no problems, but nobody has crashed with the race style and had problems (well, maybe a few, but still).
order from kneedraggers or wherever and have them sent to the lettercarrier in Pt. Roberts so you don't have to pay brokerage and duty. (provided your willing to sneak em' accross the border)
