Spiral balance for double hung windows

Home Owner from Oahu
I have double hung wood windows with broken spiral balances. The 2 photos are attached: One with the balance itself and one in the window itself. They have blue knobs on the bottom of them. Do you have these and if so, what do I measure? Just the long metal tube portion or something else?
thank you,

Hello,

Take a look and compare the 5/8" diameter S500 spiral balance with a blue tip option to your assembly. To determine the length, you'll measure just the tube, not including the spiral that extends from it. Thank you!
