73 duster slant 3 on floor ?

Whoever told you that set up did not exist did not know what he (or she) was talking about. I owned a 1973 Duster with a slant 6 and 3 speed on the floor. A buddy of mine purchased it brand new in San Antonio TX and shipped it to Germany in 1974. I bought if from him in 1976 and shipped it back to the states in 1977. Great car and ALL ORIGINAL.
