Gotcha, I just saw a post about some 70 dollar kit, and some fangled spare bracket concept and thought about the K.I.S.S. concept. 5-15 bucks and you are perfectly safe. The funny part is the only thing holding all that stuff on your roof is 4 tiny screws...
Well I've got the $70 bracket as well as the straps...and yes, the fact has not been lost on me that it's hanging on by 4 screws on a plastic roof rail....
