I'm getting myself so confused--I thought in previous research this was doable, but now I'm not able to find the threads that I thought showed how to do this. I have purchased a set of 2WD Blazer Spindles 98-05 and new sealed power hubs. I'd like to run the 12"LS1 rotors and aluminum calipers to fit under my 16" GTA wheels. If someone can shoot me so links as to how this can be done I'd appreciate it. Thanks!
