you already have one single seat in the back. find the other at a junkyard or something.. easy as cake
So, in other words you're saying in order to do this, you need to by the single seat back seat (passenger side) and swap it out for the drivers side double back seat? I'm assuming you'd need to drill new holes for the bracket to bolt up. I just need to get my old back seat out, the torx head on a bolt is stripped.
