Sliders are generally universal, and are meant to bolt between some sort of seat base (something made by planted, sparco, wedge engineering, etc) and the L-shaped brackets that bolt to the sides of the seat.
If you want a sliding rail you will want to buy aBuddy Club, Nagisa or Bride sidemount rails for specifically for a 240sx as those will be low, sidemount brackets with sliders. You can search on here for reviews.
If you don't need the slider and want maximum low, planted makes some fixed sidemount rails that should work, or you can spend money on the Street Faction bracket.
Seat mounting is generally a pain in the ass and because there is no standard to seat widths/heights, and everyone likes to sit a bit differently, there's a lot of grey area in easy solutions.
