MW Window Balance Springs

A home owner from Oakton, Virginia says:
I have MW double hung windows in my house. A number of the balance springs have come loose from the window and/or the sashes. One or two of the plastic attachment hooks on the bottom of the windows have broken. Will any of your replacement springs/balances work in these windows?

Hello! It's hard to say without seeing photos, since MW uses many different types of balance systems. Our 20-004 or 15-104 may be similar to what you need, but I'm not sure. What do you think?
A quick learner from Oakton, Virginia says:
Paul: Thanks for the "leads." I think I will wait for a little milder weather before I pull the window out to check the precise spring action. - John D.
