I did an "article" about mine

I have 2nd row bench and 3rd row split bench so I wouldn't be intalling a seat in the middle. I do think that it's possible if you don't have a split bench. There's plenty of room between any two seats when I install them outboard in the third row.
As for the missing belt: is it the buckle that's missing? Mine has disappeared a few times and I've had to remove the seat and fish in with my hands thru the hole in the seat and thru the bottom to get it. It's a tight squeeze and a PITA.
firemom-- have you tried moving the seats all the way forword before installing? It shortens the buckle stalk in my third row when I do that :twocents: I've gotten my EFTA back there too, it takes considerably more work and the seat needs to be all the way forword & three buckle stalk twists to do it though.
For both seats I have to recline the vehicle seatback to tighten the install all the way then put them upright again.
Overall I really like the van. I think it has awesome visibility. I like the way it handles. I purchaced mine from an old dude who didn't change the timing belt and TENSIONER at the prescribed time. 11K miles later (at something like 76Kmiles) they failed and the motor was ruined. So mine now has a motor from an 2004. It's got 95K miles on the ODO and maybe 55K miles on the motor. We've had no issues. Oh, we have one issue-- the airbag light is on
I'm scared go to the dealership and have that delt with
