Astro Ventilation

Ok, this may sound like a strange question but, does anyone know if GM ever built a mid 70's coupe without the Astro Ventilation system? My 74 does not have the vent box behind the seats where the air flows through. When I look at the rear end from underneath the car, it appears to be original, and I don't see evidence of the rear deck ever being replaced.
Every 74, or pic of a 74, I have ever seen has the Astro Ventilation, but I can tell you that mine does not have it.
