I have an old air unit in a 62 falcon. It works fine. I have some definite air leaks to fix before i even consider a/c. I thought the heat was just radiating, but I noticed a hot draft while driving and looked and saw that the felt was out of place where the choke and throttle cables go through the firewall. I'm sure i would love driving my truck more with it, but I'm not sure i'll be happy with the looks of it and i would like to keep my cowl vent (I was considering a under dash evap.)
