I used the Vintage air kit in my '53. I thought the instructions were terrible, and neither my e-mail or call to their tech center was returned. It's not that cold either, just OK would be my best description. Should be a meat locker for how small the cab is, and with all the new seals and whatnot. I took it back were I had it charged and they said everything was as it should be. Maybe I'm just a picky idiot who can't read instructions, but for the money I just ain't happy.
