Replacement spring ends needed

Question

These photos are of a complete spring with ends. I have a broken end on the other spring. Any Idea where I can get replacements?

I know this system. These came out of a jamb liner. Unfortunately, you need to replace the complete jamb liner system. Take one jamb liner and both sashes (unless you only have one sash that moves!) to your nearest millwork (check Google) and they will set you up with a new set.
