I know one is the 260....2 windows down 60mph gettin' on down the road
I also found this awhile ago when I was researching how to keep me cool in that cab and not have to spend $1200....BEFORE I restored the truck...now I think I'll get a vintage air system
BUT....Check this out....it's the old fashion Box-o-ice AC unit for $300....

Kinda neat....anyone have/ tried one of these???
It could serve as a AC in the summer and a console in the winter!!!!LOL
