Block & Tackle Balance with Unknown Sash Tilt Pin

I have attached a picture of a damaged sash tilt pin. I need to replace my 34" 34B block and tackle 795 model with broken sash tilt pin and damaged pivot lock shoes. I was going to order your standard 795 model, but the recommended sash tilt pin (26-021) is not the same size as the original pin and would not fit the holes in the bottom of my window. I have looked through your hardware section and can't seem to find a match.

What recommendations do you have?

Thanks
