Both pivot points on a Loewen Double Hung broke off

I have a Loewen double hung window in which both attachment pivots for the lower pane have broken. The balance springs for both sides have now spring upwards.

There are two wood screws holding the broken halves of the pivots on the window itself.

I'm not sure if I need to replace both the pivot points and the balance springs once they've retracted upwards, or if I can still use the same spring assemblies and just replace the pivots.

Thank you
