As far as I know they do exist for the SWB. There are two different types of load cover though. Both types appear to be difficult to get although you probably could order one from a dealer if you have loads of money to spare. Nissan 1st, the breakers, may have one or try e-bay (I don't have a contact for nissan1st but you should find them on ebay) just make sure its the correct type. There was a number of threads around Jan. or Dec. on the load covers and a member posted photos of a very nice looking load cover he made himself. Try punching in "load cover" in the search box and you should be able to find those threads.
