Shafts 3.3 or cvds???

Don't the traxxas cvd's and sliders both use the same outdrive since they're both made to fit traxxas diffs? So if you have both you may as well try both and see which you like better.
You could put the sliders on the front since they don't need to be as strong and use the cvd's on the rear. Then you have a spare set.
