I was hoping for that kind of response. Where would be the best place to find the window seals? I also need to replace the plastic sheet. I'm guessing that's the insulator. What is it's purpose?
FWIW, you can make yourself a new insulator (vapor barrier) out of some 4 mil poly, (visqueen?) & duct tape.
Look around with a search to find a contact number for Merlin @ St. Charles Isuzu, if you want new seals.
