tundra style roll-down rear window?

[ghetto_superman]

ive googled it and am not having any luck with finding any kind of roll down rear window kit similar to what the tundra has. i think that would be slick.

if anyone knows of a kit of any kind that allows this to happen, please let me know. i dont wanna have to engineer my own system (seals, tracks, trim, window shape, etc) that would be a NIGHTMARE.

and hacking up the cab isnt a big deal as i am already stretching my cab like the legroom truck (as long as the hacking ends up looking like its supposed to be there.. ya know how it goes)

help me please.
