I used an adjustable steel dowel rod from Lowes, I think it was in the ceiling/roofing area. The rod fits perfectly and almost snaps in place from the back panel onto the metal rods (in the middle) in the interior of the back of the seat. I just used two metal tapping screws and screwed the seat back, below the top of the pocket - so the screws are only noticeable when looking down into the pocket, to the rod. Although, the seat back is not as tight and flush as the factory clips, it still looks good with no gaps.
