Thank you for posting on our discussion board. For your clip, our 15-181 shows some resemblance. These can be used with the Series 190 coil spring. There should be a number at the end of the coil. That number will determine the spring strength of the coil you need. Lastly, you also want to go with our 15-182 bushing. Review all the parts mentioned and let us know if we can be of any further help.
