Randy,
I am so glad I saw your post, because I always suspected that there SHOULD be a screen on the evaporator area. One day I removed the access cover from my 1964 to see if I could determine the source of water leaking into the passengers side floorboard while the A/C was running. What I found was that the air coming from the blower was literally blowing water collecting on the evaporator past the opening in the firewall and into the ductwork. It seemed to me that some sort of screen was required to keep the condensation from blowing everywhere. I live in humid Houston and quite a bit of water collects on the evaporator. I was actually pelted with water while looking into the opening with the blower on high in the recirculation mode.
If you would be so kind as to post a picture of the screen you are referring to, I would really appreciate it.
I finally got my '64 blowing cool, but it took a while to get things sorted out. Among other things, I replaced the compressor, rebuilt the air box (Dr. Rebuild kit is the way to go for this, replaced the duct hoses, and made sure hot air from the heater was not leaking into the system and finally got reasonable cool air (doubt that factory a/c on a midyear will ever freeze anyone out on a humid day in the 90's). If your airbox and ductwork are properly sealed, the air will blow out with surprising force. I doubt that a screen would restrict the airflow enough to adversely affect cooling.
