I forgot to mention that Duster had ladder bars and coil over rear suspension with single adjustable Strange Engr. rear shocks that I change to double adjustable later, which where well worth swapping to
I also had two different converters, a 10 Inch Contintental at first until it broke and then switch to a older type 727 T/A 8 inch SS/HA converter which was a ton better than the larger 10 inch Faster and quicker and easier to drive at the track and on the street
