Here's a picture of the overhead for the air. In 69 it wasn't rear only. They used the plastic overhead to distribute the air rear to front. I'm sure not many survived as the plastic cracks. I spend a lot of time getting it to look good and work as new. I was glad it looked good...... Because even at top efficiency it was poor. By the time the cold air reaches the front it's not very cold. On a hot day, when you need air, the roof of a suburban is like a giant solar panel. Notice I even blocked the rear most outlets. If I keep my sub. I'm going to install a new front air and ducted it to the center seat.
