I worked for a Dodge dealer in the mid to late 80's. We had NOS front fenders and rear 1/4's for two door '77-78 Aspens still in stock. After a couple years working there, the manager sent them all back to the Parts Depot during a cycle return.
Around 1985, I went to a local C/P dealer looking for an NOS front valance panel, for my 1969 300 vert. They found a dealer in New York City, that had the very last valance panel left in the country(thru the dealer network)! Think I paid around $45 or so with shipping!
