      Check out David Pozzi's Site. he has lots of info on C4 disc swaps including a template for a bracket

      We have the bracket for the 12'' style, and the calipers and the caliper bracket, Im assuming we would have to get the 13'' caliper bracket that the caliper sits in to increase to the 13'' calipers and rotors, or will the stock 12'' caliper bracket work with the 13'' calipers? If we need the bigger factory ones, does anyone have a set for sale?

      My understanding is that you can use the same bracket (like the one on david pozzi's site) to adapt the drum spindle for 12" (JL9) or 13" (JL55) brakes. The calipers are also the same. However to use the 13" rotors you need to use a different caliper mounting bracket to get the correct offset for the calipers. Try http://www.gmpartsdirect.com/ for the caliper bracket. They may have it.
