Rear window with slider

[ChevyRacefan]

Is there anything available other than the old type with a 1" plus thick frame that looks like a wart on the back of the cab.
I was looking at newer trucks and they have a smaller slider glass, like 8"x "8". but flush glass.
I would think something like this would be great in our old trucks, if could be made to use the old style rubber seal that our trucks use. It get rid of that thick alum framework old sliders had and still function like a slider and could be factory tinted.
