Polaris rear panel for XP1K has changed or not avail?

I am looking for the original design, it came with a tinted window in a canvas wrap with Velcro attachments, and the bottom up just past the seat belt attachment on the horizontal rear bar had a hard plastic covering it.

I ordered from the book, and got this cheesy clear plastic window on canvas, for $260.00!! Tusk sells the exact same thing for $59.00

Can any XP1K guys/vendors help me find one?
