Looking for door lock cylinder clip 65 Dart

Pulled off my inside door panels on my 65 Dart to see why my door cylinder locks were both loose. Turns out the driver door clip was installed incorrectly and passenger door is missing clip all together. Fixed the driver door, that's all good now. Having a heck of a time finding a clip for passenger door, it appears they switched the locks from 65 to 66. Anyone have one sitting around on a shelf somewhere that they want to sell? thanks
p.s. you can see in photo what the retainer clip looks like
