Need to know what coil goes in that clip

Thanks for posting. I think we can help you replace these Coil Balances, but the best thing to do would be to see them and the Pivot Shoe they attach to out of the window. The identity of the Pivot Shoe will tell us the identity of the coil springs. You will also be able to look for stamped numbers on the coil springs that indicate the spring weights you need. If, however, there are no stamp numbers, you will need to weigh your window sash. That exact weight can tell us the spring weights you need.

See the video below for information on removal and replacement of your coil balance system.
