From what I've seen, in my 05 and the 06's that I've driven, the 06-07 3rd row seat is narrower than that in the 02-05 3rd row because of the molded cup holders alongside the seat cushion. The 02-05 has a full width cushion. Without measuring to be sure, IMO you would need to change out both sides of the whole rear panel area as well as all hardware, and it probably would not be worth it.
