I was in classic a few days ago and they have screens showing video of different installs. recently the Speed Channel, D&B and Classic did a 69 Camaro rebuild and they put the same vintage air unit in the Camaro, of courst they made it look easy. The only thing I did not like on the vintage air unit for the firbird is the center vent they give with it.
