Any suggestions for finding Fit Kits for the retired Thule 400 towers, other than the 'watch craigslist, watch ebay' adages? I've scoured the interwebz looks for Kit 2171 for 09 Civic LX. I already have a full Thule roof rack with the 400 towers, but the fit kit is for a car I no longer have. I predominantly use a hitch rack, so I really hate to have to buy the new 480 towers and a fit kit for a rack I would only use occasionally.
