I also would like to know how this turned out! Thanks!
Sorry I need to get some pictures. I was able to move the drivers and passenger seat back about 2 1/2 inches. It is now drivable for me and I can sit in the passenger side .I want to try to push the drivers side back another 1/2 to 3/4. The problem is there is a wire bundle under the carpet so to clear that I needed to raise the seat about 1/2 inch.To fold the rear seats I just remove the headrest and the seat folds fine and still have full seat travel.
