Searching for AAPC tilt sash pivot bar

Thanks for reaching out to us. This old 6236 pivot bar hasn't been made in a long time, unfortunately. The best match we have in our inventory is probably going to be something like our 26-021. This has a similar hole pattern and it should fit in your old pivot shoe, but even then it's not a guarantee. 

I am sorry that I can't offer you a more confident suggestion.
