I think we should be able to help. Before we recommend anything, could you show me a picture of the pivot shoe to which this spring attaches? Thank you!

Thank you! That looks like our 15-177 shoe, which most commonly works with our 1/2" Series 152 coil spring. Check it out and see what you think. You'll need the stamp on your old spring to determine the best match.
