I had a set of Koni Yellow on my BMW M5. The fronts adjusted with a knob, but the rears had to be removed from the car which was a PITA on the M5 with rear sun shade. BUT, once adjusted properly, they were a big improvement over stock. On a Mopar, as easy as the rear shocks are to remove, I wouldn't think twice if the price was right, but I'm leaning towards double adjustable Vikings for my 'Cuda.
