Should be similar for A/C cars. With another punch out for the evaporator lines. And maybe one for the vacuum lines. The plastic snap in pins locate it either way regardless.
Although a year ago, your post and pictures saved my day. I have a 69 Barracuda coupe, same color, and was trying to figure how to put in the firewall insulation. The drivers' side piece has pieces that I don't need and are designed to be cut off. Which ones? Your pictures solved the problem, thanks
