Well, I'm not sure that a 'kit' is widely available, but all the parts are available at your local NAPA, O'Reilly's, AutoZone, or whatever parts stores you have there, as others have mentioned. I have had good luck with Carquest stores for brake parts, and they carry quite a few Raybestos parts.
I ordered mine from Rock Auto, which was more of a headache than it was worth. I won't get off-topic with that here, but let's just say that their shipping and customer service *leave a little to be desired*.
