I just checked too. It's Toyota part #17881-73020. Even megazip.com says "discontinued". Major bummer. Looks like used is your only option. There are guys who have repaired using silicone & tape, but to me that's pretty sketchy. I still use my van for a daily driver business vehicle, so this parts situation is getting serious. My wife and I have been talking about switching to a different vehicle for this very reason. Good luck with your search. Tim
