im selling a 350z drivers seat with sliders. as ive seen its pretty easy to install in an s13 or s14 for that matter by grinding off the tabs on the z seat and the s chassis seat rails and welding the s13/14 tabs on to the z33 sliders. the seat is in great shape with the exception o a cigarette burn "very small" on the lower cushion the back bolsters and leg bolsters are in superb shape also. the seat is ther non airbag type also.
im asking 90.00 picked up in long beach ca. (i bought the set for 180)
*p.s i no longer have the passenger seat*
edit here are the pics
