The hardware in your photo looks like it matches our 15-186 spring housing with and 15-182 bushing. If I'm right, you may want to consider the 15-180 pivot shoe and Series 190 coil spring. Look these parts over and see what you think. You'll need the stamp printed on the old spring to determine the proper Series 190 option.
