This is the last thing I took off my 4Runner before I sold it so I'm giving you guys first crack at it. Its this (
2010 - Newer Toyota 4Runner 5th Gen (N280) Behind Rear Seats To Floor Barrier Divider Net – Raingler) with the hybrid mesh because our dog kept sticking his head through the holes and getting stuck on the non-mesh version. I've got an unopened mounting kit from the switch from non-mesh to mesh. This goes for $300 new with a 1-2 week wait on manufacturing and it's lightly used so I'm asking $225 OBO.
It'll be coming from Denver via FedEx if you're not local.
