OK, thanks, that's what I thought! I didn't think there would be a position with lower anchors available and no top tether. Just curious, is the reverse ever true? (ie are there positions with no lower anchors but there is still a top tether anchor - since you can still use top tether with seat belt installs?)
I had DD's seat installed outboard driver side third row with lower anchors, but couldn't find the top tether anchor right behind it. There was one slightly to the left of it (toward the center), but I wasn't sure if that was for where the center seat was (or if it allows borrowing of lower anchors) or for the seat she was in.
I don't know model/year, but the center back seat only has a lap belt and no head rest, so neither or us wanted anyone to sit there!
