Look on Craigslist for Mopar parts in Crossville, TN. There is a guy named Matt who has a lot of stuff there. He usually goes to the Music City Mopar Club's show in Nashville, so maybe you can meet him there.
@badlilred79 also lives in Crossville and has a lot of Duster stuff.
I've known Ted & Jackie Stephens for almost 40 years. Ted has always been fair with me, both buying things from him or selling him something at a swap meet. I buy ALL of my AMD sheet metal from Ted. He has invested a lot of money and time in our hobby, and we have all benefited from that. A
HUGE amount of reproduction parts for our cars have been brought to market because of Ted's involvement and he is a busy man. His employees handle all of the sales and shipping, so they are busy people too. I can see how searching for a list of parts for several weeks and then getting told forget it would tick someone off.
