That was me...
The same seller has the Lexus LX450 version for $5 more. I thought they were the same part number: 85315-60071
It arrived.
It was not an original OEM part 85315-60071. It appears to be slimmer substitute part 85325-60061, which does work, but doesn't hold the full gallon of washer fluid like the original.
Sending it back because I can buy 85325-60061 much cheaper from other sources if I wanted a slimmer version and the seller should have mentioned that it wasn't the original OEM part but a slimmer substitute.
Left is what was sent vs original OEM.
