Hi,
This might sound like a dumb question, but what should I be looking for when I open that metal patch on the firewall, where the A/C would be at. I need to know, because I'm not sure if the car is A/C or not. It is a 1969 Chevelle Malibu, that originally had a 307 cid in it.

Thanks,
Ethan Trowbridge
