Greetings, window won't stay up. I have 2 broken Springs and appears the shoe is failing. I would be so pleased if you could give me the part numbers.

Hello there. It appears you have the 15-180 Pivot Shoe, which is compatible with Series 190 Coil Balances. For a spring stamped '8' use the S190-840 8 pound spring. You only need to replace what's broken with this coil balance assembly, but if you need new housing as well, see the 15-181 Double Support Clip as well as the 15-182 Bushings. Let me know if you have further questions.
