why put the wrong year box on one of our trucks?why?

[chevy truck crazy]

I saw this truck this weekend at a car show I had seen it around but had never had a chance to snap a pict. overall its in pretty good shape but no offense its just I dont understand what he is going for with that box on there I have seen plenty of the early ninties boxes on them which I dont really like either but Ill take one of them before this. If this truck is a members id be willing to help ya get the right step side box on there.
