Hello,

Your pivot shoe resembles our 15-180. Look over the dimensions below to confirm they match your part. If so, then the coil springs would be the Series 190. See the S190-540 and S190-440 that correspond with your coil stamp codes. This assembly also uses the 15-182 coil bushing and 15-186 clip. Thanks for posting!
