Hey. I was wondering if anybody could advise me on this... I just purchased some seats from eBay (7) they are apparently genuine and I just wondered if anybody knows about the system. There is a lift up/down handle on each one that would grip to rails of some sort. Up to release and down to lock. What I need to know is what the rails are called or if anybody has a set or just some general info on the rails as I don't have them! Many thanks.
