I agree that normally the tunnel is just primer. Cougars got sound deadener on the top of the tunnel were the Mustangs did not. Both cars were built on the same line and IMHO some Mustang unintentionally got the deadener on the tunnel.I restored a 68 SJ J code hardtop that I found the deadener on. I did not replace it because I felt it was in error.
