Don't know if Nissan changed frame hole locations for the '08 longbed, but B&W does make turnovers for the Titan. They list them on their website for '04-'07. Why not just contact B&W? http://www.turnoverball.com/info.asp#fierolisa said:
I almost went for THIS but we probably will only need bumper pull. 99% sure that's a B&W, it's laying upside down in the pic.
