I was on the road/phone when I posted last. Had a chance to take a closer look. Correction: there is indeed two different part numbers for the cargo cover: w/ or w/o rear AC. Here is an '02 with 3rd row seats and rear AC. I'm guessing our side panels could be modified to accept the hangers.
On Partsouq, the rear AC version does show up as NLA but the non-AC version shows up as available in very limited quantities. On Amayama, the rear AC version shows as available. Their inventory doesn't seem real time to me though as having a couple of my orders canceled in the past. The difference between AC and non-AC appears to be the width of the actual cover.
