Classic Auto Air Install Experience

Man, this was a great read. I just spoke with CAA yesterday as I am in the middle of rewiring my 68 Barracuda, and it's also getting a G3 Hemi swap. I am in the middle of replacing all of the firewall insulation and was under the impression that the heater/AC box just used the existing blower motor hole and mounting holes. I also purchased an NOS lever/controller for the controls for the CAA potentiometer setup. Thank you to the OP for posting all of this. Do you have any pics of your install?
