Dennis, The swing-spring that is installed on all square tail Spits is a pretty weak affair and is prone to the sag that you describe. Since there are fewer leaves than the early Spits had and only the main leaf is solidly attached to the diff, even a new spring will start to sag sooner or later. (more likely sooner if you drive it a lot).
You can have it re-arched by a spring shop or reverse the direction so that the sagging side is on the passenger side of the car and your weight will balance it out if you are alone. Several people have installed air shocks on the rear that can be pumped up to increase the height of the car. I suppose that is an option. KYB shocks are gas charged and help take some of the stress off the spring by offsetting the load. But never use them on the back of an early Spit because the extra lift causes the rear camber to go Positive.

I've been told to "replace the spring itself", "replace the shocks", "do both", "replace the front coils". I had planned to replace the spring, but after reading what Greg has done i wonder if that might be the solution. Any advice, thoughts from the experts?
