We unfortunately don't sell this exact wheel. The best option we have is probably going to be our 84-017, but the design is still different. You should look it over to verify.
Thanks for reaching out to us. Our 84-017 wheel may replace your original, as long as the size is the same, but I'm afraid we don't sell anything like the plastic guide you show in your first two photos. That's very unique design. My recommendation for that would be to contact the original manufacturer of the door to see if that's something they can get for you.
