I'm afraid I know the answer to this question already, but I am still hoping that someone out there ran in to the same issue and found a solution I have a 2003 Silverado Quadrasteer (1500) and was hoping that there was some manufacturer out there that made fender trim/flares that would find the quadrasteer rear wheel wells. So far, checking with the major manufacturers, they told me "no". But, the last accessories group I called indicated that the "Step side" versions of the trim packages might fit the quadtrasteer... but he was not sure. Anyone out there added trim to your quadrasteer fenders? Either the steel trim, or the plastic flares? I've seen many pictures of modified quadrasteers where people only added the front fender trim, and ignored the back - I'm not sure I like the way that looks... Sean.
