32-4 FG5 CMC 54 Window Spring

There were two different parts on this window. The one on the left broke. The part ending in 54 is the one that is working. Can we get the one ending in 54 to match or do we need to replace both springs?

Thanks for posting. Sounds like you have a 33" block & tackle balance with a stamp option of 3240. I'm afraid that's all I can tell based on your information, though. Now you just need to pick out the top and bottom fittings in order to determine the Series.
I recommend that you look at our Channel Balance Home Page and follow the steps in order to find the Series that best matches what you have.
