Im trying to sort through the limited research that I have done. Im looking to eventually purchase a 280Z or 240Z(?) front end for my destroyed Z. The car does not matter at this point, the front end is what I need to know most about. I have seen pics of Z fronts and they all differ. Is there a major difference between the Z and ZX front? Am I looking for widebody (see pics below)? Where should I start looking? What fronts are these? Here is what Im looking for:

Any help at all is appreciated, thanks.
