I am wondering how many fasteners were used to attach the Firewall Insulation on a early '67 Coupe W/O Air. I'm getting some conflicting information. Some of the Dealers say you need 4, I'm looking at the 67 AIM - UPC 1 pg. A6.5 it shows only 3. I saved 2 taking the car apart, the one in the middle and the 1 lower right in the diagram. And I believe I found the hole for the one at top
above the accelerator. Any body out there know, is the AIM correct? Or is there another one somewhere?
