No one else mentioned that the 1998/1999 change of 8 on 160mm to 8 on 170mm! Our trucks are 8 on 160mm (in modern terms,) NOT 8 on 170. The 8 on 170s WILL NOT work!
I agree with JiMerit that the Econolines are the best source of good wheels, but watch out for 16.5s which are more common, around here at least.
@ whitedog; I strongly suggest that you reread the material in your second link. I stand by what I said.
