$30.95 each. The fender name plate that says Dart is $26.95 (FD330) each and the emblem retainer is $7.20 a set (FJ 343). Pg 300 in the 66-74 A/C body catalog.
NOOOO! They cost $30.95 EACH, meaning if you only need one you will pay $30.95. If you happen to need two you will pay $61.90. These would cover your rear quarter panels. Now if you need the front fender emblems that say dart you would pay $26.95 for ONE and you would probably need the emblem retainers so you would pay another $7.20 BUT this is where you may have gotten confused. The emblem retainers come as a SET (which means 2). You only need to spend $7.20 one time and that will cover both fenders left and right.
So if you need both emblems that say DART on the fenders $53.90
and both emblems that say SWINGER on the quarters $61.90
and one pack of emblem retainers for those Dart fenders $ 7.20
You would pay a total of $123.00
