      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.
