Busted Pivot Bar and Pivot Lock Shoe

I have a few vinyl double hung windows that are showing their age. Aside from the bent pivot bars (in some) and a few crack pivot shoes, the windows have held up. While I would like to replace the parts that have pasted their prime, I unfortunately don't know the manufacturer. I hope your assistance can help me. Found 15-135, which I believe is a match for the pivot locking shoe I need. While I continue to search for the pivot bar, could you be so kind to let me know if you have one compatible (as a secondary option).
