If you want to a new tailgate operable window, new replacements from Toyota are $74.45 tinted, no defrost.
For tinted with defrost $206.32.
I had to get one for my 87' 4Runner after a little "in the half up position" misshap last year. Took a week to get to me but its all OEM brandspaking new. Shipping was almost nothing. But I had to pay tax since in Washington State.
