just buy the rain gutter less one,
look for sportrack.com i think the model is something ending with 2 (like 0002 for 2nd model)
or look for yakima Q towers kit (two Q towers in 1 kit, u need 2 kits) with pair bars(not sure bar length i think 48" ?)
sportrack should cost you 200+_ , yakima should be 300+_
and i think sportrack are owned by thule , thule sell expensive models while sportrack are budge friendly
and the color wares out and turn grayish after few months of use, i guess clear coat them might be a good idea?
