Need to get new springs on my 68 4 door, and may crank up the torsion bars a bit, or buy thicker one

If the majority of the time there will be no load in the car, careful to go too HD. The kidneys will thank you. But i if you have to have a car that will 4x and get the groceries, you could keep that horse feed/gravel bags handy to put in trunk to keep it cadillacky.
