Well looks like may need new springs after all. One of the top leaves was also all rusted out around the center bolt. Looks like water got trapped under the rubber bumper, and rusted out a 1.5" square about 1/8" deep into the leaf! A local spring guy says its usable, but...
Anybody have recommendations on a supplier? Know if any of these are US-made, good steel?
