timsmach1 10 Report post Posted December 15, 2011 hey everyone, was wondering if anyone has some pics of the firewall on an a/c 69 stang. I am trying to put my a/c box that came out of a coupe in my fastback that originally had no a/c I cut my hole for the heater core pipes but I think I need to drill holes for the studs. thanks Quote Share this post Link to post Share on other sites

Where you need to drill the other holes the firewall has small dimples where the holes need to be drilled out. I added factory A/C to my car years ago. Very easy to do, great upgrade. When arriving at a cruise night on a hot day, my wife and I are so much more comfortable. Quote Share this post Link to post Share on other sites
