In the beginning, the emblems were on the fender. At some point they were on the quarter panels, then they went back to the fenders. Maybe somewhere along the way they changed? Do they all have the yellow daisy on them? I have a pair from a 73 Dart that have the yellow Daisy.
they all had 4 till Chrysler decided they could save money and just use 3 pins. eventually they removed the flower. most had 4 barrel nuts except the 70 swinger 340 which had a nut on the flower
