I don't recall exactly which manifolds are on your truck but they appear to be later model ones to me. If so, you will probably have to go with a custom bracket or the (pricey) one that you posted the link for. I don't recall EXACTLY what year the SWP went away but I believe it was around the same time that the Rams Head manifolds went away. So, in short, I don't think GM made a bracket setup for the SWP and the type manifolds that you are running. Keep in mind, this is just my opinion.
