93' Dually rear power window

I'm looking to make the rear window roll down on my dually but can't seem to find the kit for it. Not the door windows, but the extreme rear window. I have been searching for a while. Does anyone know where I can find the kit. Thanks for your help in advance.

there isn't a kit for the window of your truck and the ones you have seen that are not on new trucks are one offs custom made(kits) and with your window being glued in makes it a little more challenging but not impossible
