Pivot Bar 2318

Thanks for posting. I believe you might be able to replace this pivot bar with the 26-360. So long as the pin that fits into the window balance shoe matches up, and so long as at least one of the mounting holes used on the old pivot bar aligns with one on the new one, then this should work for you. See below and let me know what you think.
