You should be able to order it from any Honda dealer parts department. Be prepared to pay though. Part number should be 42700-TGG-A71. You are probably better off getting a good aftermarket wheel for the same price.
I was originally going to post the same as 360glitch and say to watch the forums for members selling theirs, but now you've got a VERY convenient option.
Don't bother holding out for brand-new rims. You won't gain much, if anything, other than a lighter wallet.
