You have a challenge with the floor difference, mine is flat except for a couple of crossbraces. I measured the position of the seat in my wife's CRV for angle of the seat back since I know that is comfortable on long trips. I am going to use 5/8" treaded rod with nuts on the top and bottom of frame at the front for adjustment. The frame lines up with the stock mounting locations with an additional brace in the center front and back.
