I just ordered the supplement yesterday, believe it or not i had the 67 Plymouth manual from the early 70's when my dad got it for a car we had in the family. He worked for chrysler as a rep and got me manuals for every car I had which I still have, 60 Desoto, 63 Valliant, 66 Plymoiuth, 67 Plymouth, 69 Plymouth, 72 Charger, and I also have a 1960 Desoto Parts book. Thanks for taking the time to respond.
