Rear Window Louvers

[foster]

Does anyone have rear window louvers on there truck and more importantly where did you get it? I have a sliding rear window but am looking for one without the hole for it, I only open the rear window to let air pass through and am looking for a custom look and more privicy without using tint that will fade. I have seen them on many trucks but can't find them. I have a 91 but I think the rear window was the same for many years. Thanks
