Bart is 100% correct. The hard part will be getting the towers and winged crossbars. Once you have those, there are numerous options for baskets, storage containers, bike racks, etc. from the aftermarket.

For the towers and crossbars, you could search online for wrecked VXes or wait until someone puts some up for sale here (very rare). I don't recall if anyone was actually successful in fabbing up their own towers and bars, but I imagine there are a lot of potential customers if someone mass produced them...
