pictures of under dash a/c unit?

[la hi]

I have a 57 swb and I want an under dash a/c unit. I do not need the full inside system like vintage air, the under dash surely will cool the small truck even here in central TX.
The edge of the dash is 8" from the firewall in the middle of the cab, and they say you need 12". That means you have to have 4" sticking out and I would like some pictures of your install to see what it will look like.
thanks
