Up for sale I have a pair of seat brackets made to suit a 300zx. Purchased from NZKW. (click for link) I was using these with my old bride seats in both my 2+2 and 2+0 so can confirm they fit both. You will need universal sliders that go between the seat and the bracket, or if you're confident make your own adapters so you can have a solid mounted seat. With the sliders, these sit a bit higher than the extremely low mounted bride rails, so it's good for short asses haha. Looking for $170 ono with pickup in Baulkham Hills after 4pm and weekends or Macquarie Park between 7.30-3.30pm weekdays.
