No, that is not an A/C firewall, this is a heater only car...
Sorry it's not still in Florida, I live up north and drove it here back in 1988 and have owned it since... I had been looking for a good 340 Barracuda for 10 years before I finally found this one... I had many Barracudas, but this is the first original 340 car that I was able to acquire...
