AC Retro Fit in 78 Z

Since moving down to FL, I'm at a point now where I want to install an AC unit into my 78 Z28. The car originally does NOT have AC so nothing to work with. Where's the best place to either get a complete underdash unit or do I find a 78 w/original AC at a yard and gut it out?

Have you tried a company called "vintage air"? A google would probably find them. Or you can try Year One.

Thanks RedFrormula1, I really haven't tried anyone as of yet but will do a search for these. :)

vintage air has some good stuff, but your going to be looking at over $1300 for the stuff....
