1970 Duster 340 Decal Placement

I wish I could find my pictures of my brothers 1970 340 Duster. He bought it new and it never had a 340 decal that I remember. It just had Valiant/Duster on the fender and the Duster cloud on the back. Just the grill was painted black in the center and gray on the outside was the only you could tell it was different. That and two tail pipes... turn downs. I could be wrong it was along time ago, but that's what I remember.
