I have a broken coil balance to replace off an MI #1555 window, left side. Inside the cover is stamped 8, spring is stamped 732. Width is 1 1/4, depth is 9/16 & distance between the 2 mounting screws is 1 1/4. I will replace both sides if you have a part that fits.

See our 15-180 Pivot Shoe, which uses Series 190 Coil Balances. The stamps on the springs themselves are what relevant. A coil spring stamped 740 means you should use the S190-740 7 pound spring. Let me know if you have any further questions.
