On another Mustang forum, I noticed a discussion about underhood insulation on '69 Mustangs. I realized that I have no idea about which cars, if any, were actually produced with this insulation when these cars were new. I've read lots of differing facts, most of which are pretty contradictory. Which models actually received insulation from the factory? Would my car, a June 5th-built Mach 1 from Metuchen, have had it originally?
Thanks! This was just one of those late night, couldn't sleep, had to know, questions!
