Chrysler kept the Valiant badge on Duster's in '70 because they did not know how well the new Duster would do as far as selling(next to the Valiant which did well) so it was more or less experimentation to see the buyer's reaction. The Duster did well and the Valiant emblem was dropped for '71.
This is still a nice car and I'd love to own it. I'd never advertise it as 100% correct when it is indeed not.
