Not possible with the smaller center hole. Perhaps you can manage to cut them out. Or you have the rotor and axle pilot machined smaller.I think a lot of guys just toss them on without spacers, no?
Crazy, I never knew that. How much wider are they? I was actually thinking about swapping over to coil springs and going with the newer axles when I was replacing my old diffs. Good thing I didn't pull that trigger! Lol
