Used to be on my GMT400 I got rid of. Still in decent shape, just need some double sided tape to mount, and I may even have some laying around to include with it. I'll have to look. Will get pics and measurements next time I dig it out of the garage. Absolutely great for rear sliders. Keep the window open and the rain out. Also adds privacy, shade and looks. May even fit a square body, not sure though.
I did a quick search, cheapest I see is 28 bucks for a new one, I'll let it go for 20 bucks shipped to lower 48 or trade. I actually paid 80 bucks for it, but that was my pre-digital days. :help:
