A lot of sedan owners have swapped coupe seats in the front, the wiring usually needs to be spliced to get all the functions to work but they bolt right on. I bought a set of coupe fronts with the intention of changing them on my car but they were in worse shape than I thought they were so I re-sold them.
350z seats are also direct fitment.
