Unsprung weight is going to depend on what you are using for axles, tires, wheels, brakes, and so on. Only you can answer that question.
Did you happend to notice that this thread will have it's 9th birthday on next saturday? And if you had looked the OP's profile, you'd know that he's not been here since 2007. So don't hold your breath for an answerI just came across your post and was wondering if you could tell me what you came up with for the unsprung weight of your dodge dakota? I could not see the images you posted in the link. Thank you!
