Thanks for posting. Please look at our Series 600 spiral balance, 15-152 pivot shoe, 26-360 pivot bar, and 26-393 tilt latches. Carefully compare this hardware to your own and see how well they match. If they don't, please take pictures of each part you're looking to replace. Make sure they are fully removed from the window before you take your pictures. We will also need detailed dimensions as compared to the parts I've suggested.
