Does a '69 air cleaner look wrong on a '70 Dart Swinger 340

Back in 1970, I bought me a barely-used 70 Swinger 340 also with a 4-speed. It was Panther-Pink and I think I still remember the serial number;
LM23H0R321200
Well almost. it seems Ima few placeholders out...............
I had a factory pink 340 auto.
