Looking thru the dearborn assembly line photos on the site I noticed that in image 37 it shows a 70 mach1 with black underhood insulation. I tried to enlarge the image and it appears to be a non AC cleveland car but I may be wrong. My 428 Mach1 had the black plastic clips installed underneath that held the insulation up when I bought it in 1983 but no mat. ( the car had 53K hard miles on it.) My question... Does anyone have any thoughts of ideas on which cars got insulation?? This is one area that seems to recieve almost no attention from the resto community and I'm guessing that there is nothing available if your car had insulation originally....
