I pieced mine together from a couple different stores using Thule parts. Parts you need are:
Thule 480 Traverse
Thule LB 50
1014 Traverse Fit Kit
The 1014 is the toughest piece to find...not a single local store in the Phoenix area had it. From the little I read the fit kit for our car was always in low supply. Good thing is ORS Direct has no problems with it. Link below takes you to everything you need. Might be able to find some pieces cheaper on ebay/craigs.
This setup fits tight and true. Use it often with no qualms.
