Hello, Kamran. It sounds like you're looking for an all new balance system. Fortunately, we still carry some of the older Thermal Gard window parts. Start by looking at our 15-070 pivot shoe and the 9/16" diameter S600-22 spiral balance. These look like they'll work for your original hardware but look them over and please let us know if you had any questions or concerns. |
