I don't know specs by any means but the axle shafts and differential covers appear to be the same p/n between axles. I'll bet the pinion gear spacing is different for the larger ring gear needing a longer pinion snout.

What backspacing/offset are they? If they stick way out of the fenders, chances are your gunna have to cut a lot. Best way to figure out if your dead set on them is to buy a wheel, loosely bolt it up, and measure it out. Someone has to pull the trigger somewhere along the lines with things like this haha.
