*400xt Aero Foot PackThe original 400 Aero foot is restyled with improved looks and function.
*92 Fit KitDesigned for use with the 400XT Foot Pack. Our Fit Kits mirror your roof’s profile. Set of four brackets and footpads. (ha, that's y i said it doesn't flow w/ the lines of the 240sx, they didn't have this when i bought it back in '98)
LB50 Load BarsBase for Thule Multipurpose Rack Systems. Set of two bars. (i saw some people w/ longer bars that go out like a foot of each side of their vehicle---if you're not careful, u can "clothesline" a pedestrian/bicyclist)
477 Short Roof AdaptorDesigned for use with the Aero Foot System. Provides extra stability to the rack system allowing it to hold more applications.
(some people i've seen skip this item to be cheapos, but to get the full use of your roof if you're gonna carry anything big/heavy, u need this; it'll look to awkward w/out it as well...)
u need pics, lemme know; i gotta borrow my bro's digicam
