yeah was a full bride rail. base and sliders etc. it wasnt noticable sat in it, but looking at it from the back your could see it slightly urmm ive just use the feet and sliders from the oem rail. cut the parts that bolt to the seat off, then bolted the rail back in the car, measured out the bolt holes in the bottom of the seat and welded 2 flat bars across the rails, drilled holes, welded them to the sliders and bolted the seat on
