Sorry for the late reply just saw this thread. I tried 350z seats in my 280zx coupe, they won't work for me. They sat several inches higher and will not go back as far, I think they sat 3-4 inches further forward. If your under 6 ft they may work for you and if you have a 2+2 they will probably work. I cut the legs off the bottom of the 350z sliders as the sliders are part of the seat base. I then welded 1" wide 1/8" flat bar to the sliders at the correct spacing for the stock sliders. A better way to do it would be to drop the factory sliders and weld custom floor brackets to the 350z sliders, that would get your seat height lower but won't help with how far it will afflicts back.
