Window coil balance spring and hardware

Question

Need to replace two of these. I can see the spring has an 8 on it. Spring are actually broken but would prefer to replace the whole unit. Thanks

Hey there. This looks like the 15-180 Pivot Shoe, 15-181 Coil Housing and 15-182 Drum. This system uses Series 190 Coil Balances. If a spring is stamped '8', use the S190-840 8 pound spring. Let us know if you have further questions.
