I bought my duster around 2007 for my son to drive for awhile while I raced my Daytona. I’m not sure if the manufacturer of my rear shocks and they are probably over 22 years old. My front suspension when I bought it was a strut setup off a Mercury Capri and unadjustable. It was converted to a single adjustable strange strut over 10 years ago. So between the ladder bar and the suspension I don’t have a lot of adjustments.
