I love documentation and originality when it comes to our cars history which is why i am here. I am looking for anything that has to do with the 1976 Plymouth Feather Duster. i currently own a 76 plymouth brochure that covers all 76s and has a page for the duster where the Feather is mentioned but not advertised that well. I am not entirely sure if it has its own AD but ive seen ads for the space duster and gold duster so i have hope but if so i am very inerested in owning one and will buy for the right price. im interested in any form of ad as well. 70s style magazine ads, poster ads, etc thank you in advance for your help.
