I ordered a side panel through TXPOWERSPORTS parts ordering. Their prices are a little ridiculous, but it will be a Hawk specific part.

Another option would be to try a TT250 rear fender, the price is half that of the genuine hawk parts, and the TT250 is a very similar bike so it is likely to work, but since I have no direct knowledge it will actually work it would be a slight gamble. However, considering many of the body panels, and the seat, will directly fit on a Hawk, the chances are good that it will mount up. My Hawk already has a number of TT250 parts on it that I bought simply because the prices were WAY cheaper than the Hawks parts.
