when i purchased mine about 10 yrs ago, i remember talking to whiteline in australia. i think they referred me to 1-2 companies in the US who distribute their parts.
i don't remember the company i purchased the sway bar through, but the sway bar wore out my rubber bushings fairly quickly and i purchased poly bushings from a great company who is also on whiteline's dealer list.
Bought Poly Bushings for Whiteline Sway Bar - Also listed on Whiteline's Dealer List
