I'm not sure anybody knows what you mean by "cups", but most non-GTR skylines have 5x1 bolt patterns at the diff, and the n/a ones have 2x3 (6) bolt pattern, similar to what many sylvia's have. The hubs are the same and they are interchangable into between chassis if that's what you are talking about.
