There are 4 12mm (I believe) that hold the cushions to the frame. Two under the plastic covers (The cover that surrounds the adjuster for he seat back) on the seat and two underneath the side bolsters that hole the back to the frame. I remember these when I replaced only my passengers seat coushion and the drivers seatback. I have not done the SE-R seat conversion yet but from what memory serves me that is how it works.QuickZeek said:How would you reuse the NX rails only one comes off
one side is part of the seat.
I built custom rails for aftermarket seats (cobra Daytona)
they do sit quite higher its easy to get used to but its somthing to look out for.
unless you some how use the base of the nx seats with the sentra seats i don't think you can just swap rails.
