Does anyone have or make flip out rear windows??

I was thinking I'd like to get some ventilation thru my '64 GMC and I was wondering if anyone made flip out windows for our vans??? Did any vans come out stock with them? I could probably graft some in if I had to. Has anyone done this?
Thanks,

some had pop outs that opened a couple inches. some complain of exhaust coming threw. when I bought my van, it had no weatherstripping and exhaust would suck in around the door gaps bad enough for my eyes to water. cant imagine what a window would do.

I was thinking more for when stopped and/or camping. It would be nice to get some ventilation in there, especially if it was raining.
I also have side pipes. I'm not sure that that would make a difference but........?? But it would mainly be for when stopped.
So if some of them had them, I guess I need to do some looking.
Thanks!!!!!!!

RV Roof hatch? My van already had one cut in when I bought it. Works great, no exhaust ever comes in, sucks out heat when moving.

I was thinking along those lines but I really wanted to keep stuff of the top. I like the looks better but "function over form" may have to happen.

I found these on ebay... 18" x 22-5/8"
Off of a 1982 Chevy van...
Maybe you can get these somewhere... I just found them while searching.

Thanks Jacke. I did a couple eBay searches but no luck. I'll keep looking.
Appreciate it!!
