A/C pics for a early A

The '66 Barracuda & Valiant ( & Dart) factory AC had a large chrome piece that held three rectangular outlets, these were rather skinny (or short in terms of their height) to clear the center console. So it looks rather ad-on like a dealer installed item but it was from the factory. Also the heater controls are push-button type. AND the worst part is... the firewall is different between AC & non-AC cars. I'm sure there's someone who knows more than me that can chime in with better details.
