What shocks and springs for 74 Duster?

On my Duster, (74) I used the ESPO 1 inch over springs and KYB shocks. The ride was good, a little stiffer than stock with good control. ESPO also offers stock ride height springs.

On my Cuda ('73 4spd) I went with PST. I did a total front and rear rebuild through them minus the S/S springs. I retained the stock sway bars. There material was and still is in excellent shape 10 plus years later. The car handles wonderfully. Nice and tight. Real responsive and sharp! I would think twice about going back with them.
