Most recently...based on the above two photos, the front valance on 70 Challengers must have been installed AFTER the fenders got there coating of sound deadener sprayed on, where-as on 71 Cudas the front bumper and valance were in place because the front signal light housing was almost always covered to some degree.
On my 70 challenger (SPD 8 26 69) there were a couple splatters on my front turn signals from the sound deadener application.
I think they were in place before application like on the barracudas.
