Looking for right part of coil balance

Question

Several of my windows are not functioning because of coil balancer is broken, see pictures I uploaded, It has mark of 8, I guess it means 8 pounds. Would you please let me know which one I should order? Your help is highly appreciated

Hey there. Looks like you might have the 15-180 Pivot Shoe, which works with Series 190 Coil Balance springs. Please compare. For a spring stamped '8', use the S190-840 8 pound spring.
