If it is just the pivot shoe you need to replace, then you can consider our 15-141. Just make sure your dimensions are the same as ours.

The coil spring, however, has been discontinued by the manufacturer and has been replaced by our S152-6. The confusing part is that the S152-6 is not compatible with the 15-141. If you need to replace the spring, you will also need a new pivot shoe. See our 15-158. I'd also recommend the 33-072 screw to attach them.
