According to my serial number I am like 368 or something like that. I would check but my truck is in the shop. I definitely don't have mudflaps but jeeze... I need them.! I don't think my dealer cares for me. I gave them less than a stellar review to nissan when I bought the truck. I might have a better shot of getting a set directly through Nissan?They do come stock with flaps. And if yours is one of the first bunch xd's made and didn't have them. I would be calling your dealer about getting them free of charge of course.
