Depeche Devotee

Hi all! I will joining the Highlander Hybrid owner's club soon, as my car broker has located a vehicle that is in transit. We are getting a Limited trim with captain's seats in the 2nd row. We have a 70lb dog who will be sitting back there, so we found this company that makes custom gap fillers to accommodate our dog: https://www.dogshell.com/product/customcaptain Would anyone be kind enough to take the measurements shown in the picture for us so that we can order this ASAP? I would be immensely grateful!
