Need help please!! 70 Dart trunk emblem

Did you get the answer you needed?
I have 3 1970 Darts in the back yard and can help if you still need it.
BIG QUESTION though: Is your Dart a 1970 340 Swinger? Of the 3 1970 340 Swingers I have owned 2 Had The DART SWINGER on the trunk lid and one had only the Dodge emblem! Never have got a straight answer on why the difference.
