Here's my '64 I just bought yesterday. No engine, manual trans. The body has seen some tough times, but the main reason why I jumped all over it was the fact that it has factory A/C. I have never seen in-dash air on a '64, because I thought that the option first came out in '65. Anyway, it's got the tinted windows, but the evaporator housing is missing from the firewall. Funny, I have seen those pieces intact on parts trucks, but it's always the dash pieces that are missing. This one was backwards. I bought it off of Craigslist from a guy who was getting evicted and had to get rid of it. I bought it for $200. The Chevy truck Gods were shining down on me yesterday.
I plan on getting it back together, stock-looking, and making a cool parts chaser out of it.
