I actually had better luck getting the rods in first then getting the rails in the proper location. I pulled the seat back out on the bottom about 6-8" (the seat backs swivel from the top) and was able to get the rods in place through the metal holes in the back of the seat back. Then keeping the seat bottom snug against the seat back I could lower the seat bottom rails into place. It is a little harder to see the rail slots on the passenger side because of the battery.
