Are you specifically looking for a OEM half shaft? I'd just go to www.rockauto.com and buy a Cardone or similar replacement. They are not bad half shafts. The only reason I stay away from them is I can't use them for donor parts on my extended half shafts (inner spline counts dont match). As far as actual spare half shafts though, for the price, they are a pretty good option.
Edit: Oh, and to help you out, both sides are identical. No worries on anything side specific.
