Are you looking for the integrated booster in the armrest, or the ones on either side of the seat bottom? I have one of the arm rest boosters, swapped it out of my V70R when I traded for integrated seats.
I'm really looking for the entire bench with the integrated seats, but I might be interested in the arm rest booster as a stop-gap in case I have a hard time finding the integrated seat. PM me with a price. Thanks!
