I purchased a Recaro TS-G ASM from Japan and they included these rails and brackets. I searched for the part number on the powered seat motor subharness and traced it to an NSX. The brackets are quality aluminum and are contoured specifically for the rails and the powered seat switch assembly. It appears the brackets are universal left/right and have seatbelt mounts for either side, but the bracket looks specifically for the US passenger or JDM driver. Also I believe the long metal bars in the last pic might be designed to work with manual rails, but I am just taking a guess. Any information anyone can shed on them would be helpful so I can determine what to do with them. Thanks!
