I think that both sides are the same, but I'll let someone who has actually ordered them chime in.
I just wanted to caution you about the "green cup". Make sure that it is still intact and hasn't been scarred up due to lack of grease and road crud getting into the joint. The "green cup" is actually the outer race of the inner CV joint (confused yet?). It is the end of the axle that is in the front axle housing and it is painted green. If both of your inner CV boots are still intact then it is more than likely okay, but if the boots are split (and have been for a while) then the grease was probably flung out of the joint and road grime probably made it's way in there. If the green cup is all boogered up, then new half shafts won't do you any good. Sorry to be a Negative Nancy, because I do hope that everything is okay in there.
