When i bought my Olds, it had ladder bars and air shocks…it was a total mess and the rigid rear end wound up hammering the upper shock mounts…and bouncing your ass out of the seat. Both of those made the car ride like shit on anything other than smooth pavement and made wheel hop worse on any surface imperfections. Ripped out the air shocks and it still was a crap ride with the bars (edit and when the wheel would hop, the lack of suspension articulation after the initial hop made it even worse). Running the right spring and shock combo with adj trailing arms is the ticket if you’re not living at the drag strip.
