FINALLY GOT IT BACK!

I have owned many 71 Duster 340's. They all had the "Duster 340" decal on the back. I never saw a 70 - 72 340 Duster without it having the 340 on the back. Unless it was removed for some reason for a new decal replacement. They got scratched up very easily when leaning in the trunk area. The stripe could have been damaged and replaced.
