Good morning, Bobbie. Thanks for posting. We may be able to help you out with this. First, check out our 15-180 shoe. Does this match your existing shoe? If so, then you should also check out our Series 190 coil spring. The stamp on your existing spring might be 440. Double check and see what you think. That would be our S190-440.

You may also be interested in our 15-181 clip and 15-182 bushing. Let me know what you think!
