I need to replace these string pulleys. The stamp on the metal bar on the side of the window is: 18 2 IP (or 1P) Caldwell. Can you help? Thanks so much.

I'm afraid neither the cords nor the pulleys can be replaced by themselves. You will need a new balance. 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.
