Hi ukv33, each of my seats have two threadedcaptive nuts or whatever so that either seat can be in either location, 2011 plus 4, just put a nice s/s button head allan bolt in the spare hole or a normal bolt with a plastic cap. On the seat frame i did need to drill a hole for the seat belt stalk and the reclining lever as a little more awkward to access, but for me, worth while so both seat wear evenly
