On my CC, I got the little plastic clips that hold the bungee doubled over from the dealer for less than three bucks a piece. I will go to the store and get some bungee cord to replace the bungee in the actual strap (West Marine sells bungee by the foot). I am doing this because I am making some custom mounts for my air chair, and plan to have them and a pair of stock Flight Clips powder coated red with red bungees.
I am sure the plastic clips and the bungees to do all the flights clips will run me less than $30.
You might even be able to reuse the plastic end caps if they are anything like CC uses. I know I could have reused some of mine, I jus bought all new pieces for the sake of having them if I needed them during reassembly. If you can reuse them, then all it would take is new cord which should be less than $10. On top of that you could just use SS hog rings (west marine sells them too) to fasten the ends of the bungee.
